The impression I got was that on BAU and maybe the 12th precinct, Penelope wasn't the most active person in terms of messaging everyone (maybe Pikachu was an exception?), but when we swapped to the Strike Team, she was more active. I think Lucifer commented on this to me (maybe just because I was positive about her though?).
I definitely would consider voting for Penelope. I thought she was pleasant to talk to, even though we weren't ever really working together, and I think there was some narrative of being good at challenges, which easily could have gotten her targeted, but it never really stuck. If she's not the vote here, I'll definitely be impressed because I do think they should be worried about her winning immunity next round. She hasn't racked up challenge wins in the post-merge but she's done well in several that she hasn't won.
