Finn had been watching, but after the very first incident he thought that Chris was going to end up dead and back at the beginning for sure. There were no real feelings on it beyond that. He wasn't really rooting for the other man to succeed nor was he hoping that he would fail. He watched out of more of a passive interest, a morbid curiosity as well considering he kind of liked watching the golems get torn apart.
When Chris made it through all five tiles, however, Finn smiled, turning to greet him as he came out of the pod.
"How about a drink to celebrate?" He offered, figuring it was only polite to offer.
