The person we see in that flashback is not Balduran.
Balduran - in squid form - is lying on the bed behind the two figures. The person in front seems to be a healer of some sort whom Ansur called in for help.
You are correct. That fact clearly went right passed me. Still
said healer then seems to return at the end for some reason, or perhaps just his face. Still find it odd considering it didn't really seem like that scene with Ansur was so recent that a human healer would still look the same by the end of this game. But why would they so blatantly reuse this face if it's not important somehow?
Am I missing something here (again)?
