So people are saying that Timebomb is dead, well he's not.
In Skyrim Tale, people thought Poet died until she made a comeback at the end of Dawnguard (Ep. 123: POE IS EPIC). When Jenassa disappeared they thought the same thing, but she, also, reappeared near the end of the city.
Even though this example is from Skyrim, it can still help. Anyways people need to stop creating conspiracy theories about characters dying, it gets quite annoying.
So yeah, Timebomb isn't dead; he is not a literal time bomb. Timebomb is MIA (Missing in Action)
