I like both Karlach and Astarion with Jaheira, not super serious as a throuple but just having fun I think it's lovely 😁😁 Microbe not really but I think she lays with Lae'zel in act 1 exactly once (then she realizes there's enough fucking pain in her life, declines next time)
Microbe doesn't survive until cute Lae'zel and I think she couldn't even achieve her, Lae'zel needs a fairly pushy partner to come out of her shell and Microbe is an amoeba
