Later in the same episode Louis appears as a judge at the physical examinations for the Greenhouse applicants.
At said audition, Louis is joined by Jason who questions him on the fact that he's giving ex-con; Jackie a chance at the school, with Jason asking him to image the potential outcome of Jackie having been armed with a weapon. In response however, Louis says that he had thought Jackie was beginning to blossom at the Greenhouse. After this Louis examines Alex during his physical exam, applauding Alex's performance in the exam, before taking Daniel on his suggestion to have Alex take him on in a 1-on-1 match.
When Alex attacks Daniel, after Daniel throttled him, Louis defends his son's decision to tell Alex to leave and exerts to Hayley that they couldn't accept the behaviour Alex displayed on the court. Later Louis makes a U-turn on his decision, catching up to the Woods siblings outside, giving Alex a second chance and offering Hayley a spot at the school. Louis then watches over both Jackie and Hayley taking the entry exam (much to his son's chagrin), before welcoming the new students during the opening ceremony.
The Opening Challenge
Louis' next appearance was in The Opening Challenge, where it was revealed that he was actually the father to Eagles member; Brooke Osmond, after having bumped into Hayley in the Eagles corridor, questioning what she was doing there, before proceeding to walk up to the Eagles dormitory, to say good night to his daughter.

Later that evening, Louis meets with the 2 officers once more in his office, after they had found no evidence linking Louis's students to the missing park ranger's gun, asking the pair to leave.
However, after another search of the grounds the pair are able to find legitimate evidence, that Louis is shown out in the Greenhouse grounds. After this evidence arises, Louis is forced to allow his students to be interrogated by the officers, believing Jackie could of possibly been involved with the case and heads to the Ravens dormitory to look for her, alongside Jason and the two officers, but initially to no avail. When Jackie does arrive in the dormitory, Louis explains that that the 2 officers wanted to conduct a lie detector test.
Louis tries to appease Jackie, but Jackie refuses to take the lie detector test and so Louis is forced to allow the officers to take Jackie away. However when Hayley and her fellow Ravens offer to take the test in defence of Jackie, Louis agrees with them and beckons the officers to go ahead and to which he oversees in his office.

After this, Louis sees Eric off in the Greenhouse foyer once more, just as his daughter arrives asking what had been going on. Louis then assures Brooke that Eric had reported to him that he had found what he had been looking for, with Brooke further asking whether the FBI had found the missing park ranger.

He assures Judy that Daniel would be fine, explaining that he knew Daniel would be in good hands with Dr. Schwartz, exerting that the main thing was that Daniel had made it through the operation. In the hospital room, Louis assures Judy that he didn't know about the shrapnel in Daniel's leg, after being questioned by Judy, with Brooke then later telling him that they needed to talk.
Louis questions his daughter as to whether she really knew about the taser shrapnel, with Brooke then reminding him that she had told him that she wasn't sure, with Louis then going onto correct her, saying that she had told him that she'd seen Daniel throwing a rock into the sea. Louis then gets angry in response to Brooke's defence, remarking that he didn't raise her to be that gullible, then questioning whether there was any other details she hadn't told him about the taser. Louis then expresses to his daughter that she could of saved the Ravens from taking a lie-detector test and that both she and Daniel could of ended up in prison thanks to tis debacle.
Later in that same episode, Louis is in Daniel's hospital room, beckoning him to explain what had happened with the taser gun, before then stating that it was unfortunate he was the least of Daniel's problems and that he was displeased with his judgement after Daniel had said sorry to him.

Louis later meets up with Jason and Judy in the foyer, exerting the fact that he hoped Judy wasn't there to try and convince him to give Daniel the captain role back. However to Louis's surprise Judy is in favour of Louis' move, with Judy explaining that her son had made a mistake and deserved to pay for it.
In the same episode, Louis meets with his daughter in his quarters to talk about Daniel and to see how she was doing. Louis also thanks her for also not trying to convince him to give Daniel back his captainship, with Brooke remarking that she had figured that if Judy wasn't able to convince him, then she wouldn't be able to either.
In Swimming Lessons, Louis tells his son Jason that he wasn't ready enough to take on more responsibility after he'd asked to take the Ravens to the NASA satellite launch, upon hearing that Louis had received invitations to go and see it.

Later Louis meets with Judy in the Greenhouse cafeteria to talk about the invitations to the satellite launch.
Louis reveals that Brandon Thomas had invited him and that Brandon would be giving a speech in Ryan's honour, as Judy calls it an honour. Louis then takes time to listen to what Judy had to say about her son Daniel, after he revealed that Jason had asked to go in his place to the NASA satellite launch, with Judy talking about what had happened with her son's swimming lessons.

Guilt Free Cupcakes
After his daughter and Alex had been rescued from the missing park ranger, while investigating around the Cave entrance, Louis is seeing the pair in his quarters in Guilt Free Cupcakes. There he's notified by Eric that the missing park ranger had indeed been the man that had confronted Brooke and Alex, with Louis then asking Brooke why she hadn't just told him about the ordeal that night, as the pair could of been killed. Annoyed, Louis then just states that the park ranger saga was over, before escorting Eric out.
Later in the episode, Louis is seen welcoming both the Eagles and Ravens to the Harvest fair, explaining that a wealthy benefactor had gotten in contact with him and had been told that they money raised through the cupcake sales would go towards buying spots for 20 kids to spend their summer at a STEM summer camp program, with 200 gourmet cupcakes needing to be sold in order to accomplish said goal. In response to Max later said, Louis states that they had an alumni that had sold their start-up to Apple and that for every cupcake sold they'd retrieve 1,000 dollars. Louis then explains that once a cupcake got sold, the teams would need to ring the bell at their booth to inject more money into the sphere.
Louis concludes by saying that each of the teams would need to be creative in selling their cupcakes and that the winner would take the reigns of the Halloween dance, with the losers having to clean up after it. Once the challenge concluded, Louis gathered the students, telling them that they'd both come up with brave and unconventional ways of selling cupcakes and that they'd made 150,000 dollars, meaning they had reached their goal. Louis then reveals the winners to have been the Eagles, before announcing that their anonymous donor had a friend who was a fashion designer and that she had agreed to match their 150,000 dollars if they did a Greenhouse fashion show, meaning they could get 40 spots instead of the initial 20.
