Mmmm, no worries. Namine and Terezi threads move at a gradual pace, so you're actually at about the right time here. So, in conversing with her, Terezi's reaching the conclusion that it's a bad idea for her to go. In all likelihood, she'd have bad flashbacks, and she's done ssome sniffing around already, so she doesn't know what another half hour protected will do.

I apologize for getting hopes up here, but she'll probably sit this one out, though I'd be interested in doing something with Shen Wei in future events.
