You know what? I going to add one more person to this whole love affair. The best love interest for Kat is Michael from the long live play commercial. Who better then the gamer that is loved by all the playstation characters?
Well he is a gamer. Maybe the world of gaming works like Adventure Time. There are thousads to millions of universes that can be connected (crossovers) & there is some central universe that all video game characters live I when they aren't "working" in their actual games. That might be where the bar is. Anyway, Michael probably has an avatar that they know about, thus knowing him in real life. It is possible that the TV works like a two-sided mirror where in the central universe, game characters can see into our world, yet we don't know they can see us. Plus, Michael isn't thhe first guy to make it up on the wall. There were hundreds to thousands of proud gamers.
