Finn tilted his head slightly. "Not yet," he answered. "You've been doing this all morning?" Walking up to the man, hands in his jacket pocket, the magic that created such a thing was very much not of the galaxy Finn knew about. It was curious. He had not really befriended any new people beyond his roommate- in the way that they were both insomniacs and being up at all hours was bonding in a way. So, Finn did not know much about the universes that saw this magic as normal. The Force was its own magic, but not like some of these other places.
"So, you just jump through and end up somewhere else? How do you get back?" Finn wouldn't be against jumping through. Obviously, he made questionable decisions based on his friends. He probably would not have thought to even try to enter a mini black hole like portal.
