‘Scrubs’ Season 2’s Returning Character Can Finally Pay Off 17-Year-Old Twist

I’ve been noticing a lot of social media posts from the Scrubs cast lately, showing them in the early stages of shooting the revival’s second season. As such, I’ve started pondering in earnest about what Scrubs Season 2 (or Season 11 if you’re a purist) could have in store. While certain storylines are pretty easy to predict, at least in the abstract, there are other potential arcs that could also unfold when the beloved medical sitcom returns.

One storyline, in particular, would pay off a Scrubs twist that’s barreling toward being two decades old. It all comes down to the more-than-likely return of Ken Jenkins as Dr. Robert “Bob” Kelso. While it hasn’t been officially announced, showrunner Aseem Batra has spoken very confidently ahead of the Season 2 renewal, saying that if the show were to return, so would Kelso. So I’m feeling good about Sacred Heart’s former Chief of Medicine showing up this fall. When he does, I expect the writers to strongly honor one of Scrubs‘ most rewarding character developments, which came to a head in 2009.

‘Scrubs’ Already Set up the Perfect Reason for Dr. Kelso’s Return

Dr. Cox (John C. McGinley) and Dr. Kelso spent the majority of Scrubs at each other’s throats. With Kelso serving as the hospital’s actual boss, many of Sacred Heart’s doctors and nurses saw Cox as their real leader. There was still a lot of respect given to Kelso, given his position and experience, but he was always butting heads with Cox due to the head-over-heart battle that exists in so many workplaces. Kelso essentially had a business to run, and Cox was more focused on patient care.

It wasn’t a dynamic that was ripe for friendship. However, once Kelso retired in Season 7, there was a gradual shift in how the two interacted. It wouldn’t be until midway through Season 8 that the two would begrudgingly admit they had become friends. Without the professional strain between them, the two discovered their shared experience had actually brought them to be quite close. They tried to hide it, which led to a few funny moments, but it eventually became public knowledge. JD (Zach Braff), predictably, was more than a little jealous. Regardless, with Dr. Cox undergoing treatment in the revival after that emotional autoimmune disorder diagnosis, it makes perfect sense that Kelso would show up to lend his moral support.

Even if life has taken them in separate directions in the original series, I would imagine they have kept in touch. Cox has already proven to have softened emotionally in the Scrubs revival. So, although it would once have been out of character to tell Kelso about his diagnosis, I think it’s something he’d definitely do during the show’s current era. Similarly, Kelso would almost definitely answer the call for support. As well as some tear-jerking turns, I’m hoping for a comic masterclass that’s essentially the medical equivalent of too-many-cooks. A sick doctor, being treated by a doctor, whose friend is also a doctor? Sign me up.

Where Was Dr. Kelso in the ‘Scrubs’ Revival’s First Season?

Kelso never appeared in Scrubs Season 1 for a number of reasons. Perhaps the most prominent reason is that ABC only ordered a nine-episode run. With so many new characters to establish and familiar faces to catch up with, the writers were tasked with prioritizing who to showcase. Because there was no solid reason for Kelso to still be around by the time of the revival, Jenkins’ return was delayed. Thankfully, ABC’s decision to renew the show opens up the chance for him to come back.

While Kelso didn’t show up in the flesh, it was at least revealed that Sacred Heart had named a hospital wing after him in the years since his departure. That was a nice touch. In terms of an in-universe explanation for Kelso’s absence, the answer is pretty much the name. He wasn’t around because he didn’t need to be. While he spent much of Season 8 hanging around Sacred Heart eating muffins, unable to let go of his time there, stepping away from his former role was something he made peace with by the time the show ended.

He returned to practicing medicine elsewhere on a part-time basis, but over 15 years later, I doubt that’s what he’s still doing. If we use the canonically irrelevant Med School episodes as a loose frame of reference, Kelso transitioned into teaching after the death of his wife. Even if that is also true in the reworked timeline, I once more doubt it’s something he’s still actively doing. I assume he’s just enjoying retirement in a way only Dr. Kelso can – we’ll just need to wait for Scrubs Season 2 to arrive so we can find out.
