So I've been thinking about the whole who's gonna stay in Tartarus thing, and I was wondering, could Nico close the doors then shadow travel out quickly before he got captured? Also, couldn't he shadow travel out the first time he went to Tartarus? I know he might mot have been able to because he was captured though.
