Oh God, poor Morgana and Aithusa :( Every time Morgana refers to her and Aithusa being locked up, I can almost hear my heart breaking.

There are pics on Tumblr of Morgana with the bald guy, so I reckon she's working with him and therefore he wasn't her capturer (as I don't believe she would be working together with the man who has locked her up).
