So I got options here...

Either Constantine and Morgana hightail it out of there using Constatines great speed OR Morgana activates Warlock mode in advance. Which she previously never did in front of anyone at the clocktower. So Option A to not reveal trump seems best. I'd go with that.

Onto Locusta, Just abuse that Rank A speed grab Albert and run... OR drop her first noble phantasm on the spot and murder some elite magi before running.
