Re: Avengers Tower
[He's talking to a cartoon right now.] Time stops wherever you were when you show up here. Whenever you're sent back you'll pick up where you were with no memory of this place. It happened to two people from my world already. They reappeared here and regained their memories of the town after returning.
I've been here for 4 years, there's no known way to get home. If Stark had the means, he'd be back already. This is his lab and it's full of weapons that he uses as Iron Man to protect civilians from threats. I don't know what a collider is, but if there's anyone to talk to about it, it'd be him, Banner, or the other versions of Spiderman.
I don't know what else she told you, but Anubis volunteered to be here. She stays with her adoptive family and came to us to help control her powers because she was used as a weapon to kill everyone she loved in the last dimension we got stuck in together.
Now, do me a favor and reach into you pocket to see if there's a paper assigning you to housing or a tablet. The paper will tell you who's responsible for you while you're here and you can use the tablet to see if there's anybody from your family here.
Come on. [He picks up his shield and opens the door so this invisible cartoon boy can walk with him]
