In Everything She Wants, Emma and Mr. Simpson are talking about how Mr. Simpson is using the S.T.O.P. routine to come back to Media Immersion. And when he is talking about that, Emma brings it up and he accuses her playfully of looking at his flash cards, and she notices Sean coming up to the school and carrying a bag. He wore his army uniform and waved at the two. Then Emma tells Sean that she has a boyfriend, Damian, and he is glad that they both moved on. Then Mr. Simpson brings up the fact that he could use some exercise, and Sean offers to make a calisthetics routine for him, and the two of them go to the Degrassi gym the next day. Sean pushes Mr. Simpson too hard, and he rushes out when Mr. Simpson tries to help him overcome it.
Back at the house, Sean opens up to Snake about how he is being shipped out to Afghanistan the following day and that he is terrified. Snake tells him that he is doing a good thing and making a sacrifice to get there. The next day he comes down, and gives the Nelson-Simpson family a box and holds up the photo of Emma and him on their first date, and asks if he can get a new photo to show his platoon, and Emma agrees. They then take the picture, and that's the last that was seen of Sean Cameron.
