Correction: a character who may be an incarnation of Allen and is assumed to be because they share a name.

As well, if it was due to the intervention of the Key, Lust wouldn't have been around for a long time and would have affected more than just those two vessels (Gallerian was shot by a golden bullet confirmed to be Wrath Vessel, for example).
