I thought the very same thing and it had to be a personal choice that she made because I've seen her in other things where she was captivating and wonderful, so I feel like this was an error in judgment on her part.
Also, this is probably a huge stretch, but did anyone notice that between Copy Kane coming back (bc that's how I referred to him in my mind) and sitting at the table very stoically not touching his water, to Post-Shimmer Lena sitting in quarantine not touching her water, does anyone think that's a thing? I get that it's a stretch, it's just something I noticed on the second viewing just now. I also don't get the difference between the tattoo and the vines showing up in Josie. Is the tattoo what lead to her turning into a flower person?
