Thinking about when Dana mentioned that most her friends left due to COVID and how few old timers we see.
Like aside from her, there’s Lena, Tim, Sophie and Jesse, who is actually the youngest of the bunch since Ned is in his late forties.
That’s the entirety of the ones we see most frequently/have names for. Those are the remaining old timers who didn’t just start right before/around the time of the pandemic like Perlah and Donnie.
Like outside of the actual friends who died and the ones she probably doesn’t see any more because they left and she can’t help but help at the Pitt, those are who remain from the before time.
