If Vincent comes back Quinn is going to regret it I can see him being the grandparent that will reveal Quinn's inner thoughts. Maybe telling Layla Quinn thought she looked good when he saw her in that sleep wear one time. It will be chaos and can see him speaking up embarrassing him forgetting he is no longer in Quinn's head when he should be quite.
Surprised Vincent didn't react to the Talen Quest. Thought for sure his name come from Vincent's wife and ended up passed down. If it wasn't her name then one of Vincent's descendents must have married into the Talen family. Also anyone else have an ominous feeling Jim will use teleporters once they discover the dragon after all the vampires built the teleporters but we see only Dalki travel by spaceship so they might be keeping that in reserve.
