Well, I do think, that things between Minthara and Halsin are a bit different. While Morrigan is just bitchy and Alistair in his endless naivity an easy victim for her insults, Minthara had Halsin locked up with the intention to torture and murder him and then attack and murder his people. If I were Halsin, I would just kill her on sight and not tease her Morrigan/Alistair style. I don't see, how those two would work out realistically tbh.
If;
Halsin can forgive Kagha who was willing to murder Arabella and send all tieflings to their deaths while also giving away the entire Grove to the Shadow Druids, then surely he would forgive mindcontrolled Minthara who breaks free from the Absolute's shackles. He is a reasonable man after all and there already is such a relationship in the camp between Shadowheart and Lae'zel, who end up making peace eventually.
Naturally it wouldn't happen instantly, both Minthara and Halsin would be at eachother's throats until we bring Halsin the book from Moonrise which describes exactly how Minthara came into the Absolute's service and proves her innocence, which is found in Ketheric's own private chambers. Bing, bang, boom. Both happy campers
Minthara simply does not deserve to be discarded as a throwaway companion who isn't even inherently evil. She's such a brilliant intricate character in my opinion that deserves to be with the rest of the gang.
