WARNING: The following contains spoilers for Season 4 of Atypical, now streaming on Netflix.

The fourth and final season of Netflix's Atypical is definitely a tear-jerker, with Keir Gilchrist's Sam figuring out his short-term future and taking time off from college to head to Antarctica. But as much as it's heartwarming to see the family making big decisions with him, the show does a major disservice to two characters who've had big roles in the seasons prior.

The first is Evan, the ex-boyfriend of Sam's sister, Casey. He was with her off the cuff, romancing her after Casey stood up for his sister, Beth, against a bully. They then dated for a while, with Evan helping Casey through her mom, Elsa, cheating on her dad, as well as many instances where Sam had autistic breakdowns. He became part of the family with even Sam wanting him as a mentor.

That quickly fell apart when Casey left Newton for a prep school on a track scholarship and fell in love with Izzie. Season 4 now has her figuring out her bisexual identity after leaving him but she's struggling with labels and the adjustment. Sadly, between Izzie's immaturity and the pressures of academics, expectations and a UCLA scholarship, Casey gets depressed.

Yet Evan's not the person she goes to. It's shocking as he knows her best and would be ideal to help her as he still loves her. He's supposedly a friend, yet they text just once for the season despite him working with her dad as an EMT trainee. He asks about her a couple times but their arc's dropped to the point that it's as if he doesn't exist. Evan's just relegated to a few scenes talking with Doug about mortality.

The fact that Casey needs help about self-discovery and gets it from Abby, one of Sam's friends, really feels off as well, as she's a minor character. She gets Casey to understand that she might need to go back to her comfort zone at Newton, but this is what Evan was telling her last season. It really undoes the nuance in their past relationship. Had he helped out, working through her cheating and getting her to make up with Izzie as well, it'd show great maturity and that soulmates don't necessarily have to be lovers.

Secondly, the show botches Julia, Sam's therapist and the woman he was in love with in Season 1. He dumped Paige to chase after Julia, and while they had a massive argument, Julia still kept in contact and gave advice like an aunt. She and Elsa also became close as Julia's husband left her to raise Hanzo, their newborn, all alone. Elsa was in a similar spot when Doug abandoned them after Sam was diagnosed, so Julia could have factored in as more than just a professional who Elsa vented to. It'd have been great for moms to see Elsa helping her out with the kid too, cementing their sisterhood.

With Doug and Elsa's marriage patched, they didn't need Julia for anything apart from guidance on Sam wanting to spend time in Antarctica. With Doug's depression over his friend's death, Elsa sad over her mom's dementia and Izzie's mom being neglectful, there were also so many other angles that fit Julia's counseling in the past.

Sadly, Julia appears in only one scene when Sam needs help filling out a survey for school. It's a shame because as he trains for his cold trip, making crucial choices that'd affect his future, Julia would have been ideal for it as she was the one he spoke to on this dream and who encouraged. She was there for so many formative moments and this would have also bookended their story well. More so, it'd prove that he considered her a trusted friend and that she moved past his unhealthy, adolescent obsession.

Netflix's heartfelt coming-of-age series Atypical recently released its fourth and final season. All four seasons of the series are currently streaming on Netflix.
