The rest of Killian's plan unfolded rather rapidly. He didn't anticipate that. However, returning to the manor after healing a bunch of people and discovering the monster who injured them in their bath being washed by their personal chambermaid quickened everything. Killian didn't realise Suzie was one of the darling witch's personal chambermaid, and by using her as his little hypnotised slave, she was predominantly a hostage.
In spite of that, Suzie wasn't actually under any compulsion after he ordered her not to scream. She seemed happy to do the rest without him asking her to. In fact, she was more than happy to get a little too handsy with him, but the vampire wouldn't complain. He could relax for a while.
That was until the doors burst open, and in walked the three Benett sisters. Discovering the chambermaid they grew up with 'held hostage' cleaning blood off Killian's chest must have been quite a scene for them.
Just to answer an earlier question... Killian never had romantic feelings for Evanna :) He calls her his Queen because she helped him.
Same goes for Scarecrow- I have to put this note here- his comment about marrying her and making babies with her was only to gross her out and because he'd rather have her suffer being married to him etc than killed straight away.
XOXO
