Justin was cute.  He fixed up a little tracker bracelet like she couldn't figure out a way around it.  Granted she wasn't sure how long she could snow the device, but after Justin got up and went to work she let herself connect to the bracelet and overthrow the programming.  For the time being, the device thought she was at home.  In actuality, she was making a break for it.

About an hour later she was on grounds at Xavier's, waiting for Anastasia to show up so they could go shopping, get lunch...pretty much anything the other girl wanted.  Tina was just glad for the freedom even if she was apprehensive about meeting a sister from a world where their mother wasn't the worst parent in the world.
