That's true. Maybe before the pandemic they had a different plan for Karen and she was supposed to be around a bit more. I don't think we'll see more of the Bobbseys either (maybe Gil if they really want to torture Nancy
)
Addy does seems like more of a natural fit. She worked really well with Nick and she was a really good fit with the friend group. Yeah I get why the actors would want to do something else (especially a bigger role) but I hope they don't lose Addy.
