Q: In ÜberChrononauts, what happens to Chrono-FRED or the Head-in-a-Jar when their goal is complete?

A: When you get a FRED/Head victory, you take that Mission/ID for your own, and discard both the Gadget and your own uncompleted Missions/IDs. However, if you have FRED or the Head but accomplish your own Mission or ID, you reveal your card, discard your extra, and then simply retain the Gadget. At that point, it becomes useless to you; but FRED and the Head retain their mission/ID cards, and they stay in your possession. The Head is still who he is, and FRED is still programmed to complete that Mission, so the Gadgets stay in play as usual.
