While Lilith expects to see herself opening the Vault, she'll actually be seeing herself still searching for it with her team! Her mirror's going to show her and three others doing the sort of stuff they did on a normal basis: hunting monsters, killing bandits, grabbing loot, the usual. They'll be working together seamlessly, with minimal bickering and a lot of talking, joking, and laughing. Sometimes they'll be around a tiny rest stop (Fyrestone); other times, they'll be close to a more populated town filled with a good handful of people she and her fellow Vault hunters treat like friends (New Haven). Every so often she'll do things like touch Roland's shoulder or grab his hand, enough to imply that they're in some kind of a relationship.

They'll also, on occasion, be joined by a woman with blue tattoos that match Lilith's own. However, even if Axton's mentioned that she meets another Siren, Lilith doesn't know what Maya looks like-- the tattoos will always stay the same, but everything else about the woman's appearance will regularly fluctuate.

She's not going to be ESPECIALLY mortified about the mirror and she'll definitely keep it, but she might be a little embarrassed to show it off openly. (what do you mean she has feelings for Roland, what do you mean she'd rather hang out with some losers more over actually finding the vault?!??!?) As for looking into everyone else's mirrors, she already has a habit of picking up stuff that's lying around annnnd will probably not be great at controlling the compulsion, oops.
