He'll be back at Caer Scima probably just before the deadline! Like the 13th or something, I have no issue fudging some dates haha. If she's gone before then, he spent a lot of time between the Station/Loch Noa, so he could easily wind up down there for Reasons.

(awesome! there are more great missions ahead of you, so hang in there! and yeah, the entire trilogy is like a shot through the heart :c who did you decide to leave behind??)
