The uncommon Dove - Danger! says:

If Dove is in your Used Pile and you take damage, move Dove to your Prep Area

Does Dove need to be active to use this ability? My gut says "Yes" since this isn't a cost reduction and does not say "Dove does not need to be active to use this ability", but a previous Maria Hill ruling has me second guessing that.
