So, no kill switch for the Pulp's bio-weapons. Understandable, I see where he's coming from. That said, if your going to be having uncontrolled murder beasts than why bring work home with you?.....

Anyways, Tim does seem like a non-combatant. It would likely be best for his health if he stayed in a sci-fi/arcane forge inside the base with a chute in the ceiling leading to the main part of the evil lair so that the other members of the team can just drop whatever strange gizmos we find down the chute into the tinkerlord's domain.
