I too associate Halsin most of all with very bad timing. My Gale thought it wise to maybe tackle the whole Cazador situation with full spellslots. So, while his dearest vampire was in pre-Cazador-panic, Halsin thought it was a good idea to propose his arrangement - I hope Astarion had a good laugh, at least. (I still think it's a shame you cannot get Astarion's conversation after saying no to Halsin) Then, the next morning, Mizora comes up with her suggestion .... I imagined Gale telling her to go see Halsin and then trying his best to never think about this particular series of events again. Even the game itself enjoys teasing Gale at every opportunity!
That's hysterical. Poor Gale.
Speaking of Wyll, is it possible to kiss or hug him during the epilogue party if he's romanced? Because I haven't seen anyone post videos with him yet.
