Aw, I’m bummed you left! I think the STT crew always makes a big deal when a new major character is introduced. For me, those moments feel like when a comic book character makes their debut. Like when Luka strides into the ambulance bay, or Lucy walks down the El steps. It’s just something about those moments that sticks. I don’t think they were overly effusive. In fact, they acknowledge that Abby’s quite a polarizing character to the fandom.
I think the rest of the episode was definitely dedicated to Carol’s performance.
