Imperious Sister, what to do next?(Minor Spoilers)

I have retrieved the memories from Aigul from the imperious sister, and I remember it said she wanted a rendezvous somewhere but I cannot remember where. If someone could tell me I would be able to continue the story.

She’ll be at Hunter’s Keep, iirc.

She’ll be at Hunter’s Keep if you bring the regret as a needle or as red honey. If you send it as a dream, you’ll get an event in London instead.
