I have a weird question. Why hasn't Wynn used his phone before now? I mean he's kind of decided to try and help Roxy but before that he could have tried. I don't know how much signal he would have had in the bunker but... if seems like he would have used it. I didn't really think about it when Roxy told him to look for a way out of town but the question about charging box got me thinking about why he'd need one.
