I'd bring my sketchbook and my travel art kit (5 mins), two books full of survival skills that I have on hand, my pocket multi-tool, and some snacks that would keep. All that stuff is on-hand. I'd pack a change of clothes, too (socks, underwear at least), my decent outdoor activities clothes. All that shouldn't take more than 10 minutes.
If I get to know which game world it is, I'd try and print out a wiki guide of locations and NPCs...but that's only if I have time.
Granted, I have some more skills than Ava probably does. And I don't have decent medical supplies handy like she does, either.
