In the end, everything ended well for the half-wolf, even though he was completely exhausted.
Initially, he didn't understand how Namor knew about Vinigo's crimes, which made him very suspicious of the vice director.
Could Namor have thrown up a false flag by arresting Vinigo to try to seem innocent to Luke? To the half-wolf, that wasn't an entirely dismissible possibility. However, these suspicions soon proved to be somewhat paranoid, as the reality was quite simple.
When Luke and Vinigo were suddenly teleported out of the underground, Meredith managed to retrieve Vinigo's journal. Inside this small, modest book, all the Alchemy Professor's crimes were described in detail by his own hand. Perhaps as a way for him to gloat about his own actions, maybe as a way to document everything he had done, or possibly as a way to vent his guilt.
