I loved them as a couple in X-Men 97 through when Lorna became possessed by Malice. That was peak 'Havolaris/Polavok' for me. Both have been through too much since for me to even consider them getting back together at this point. But if they should find themselves in a good place some day -- I could certainly see the spark reigniting, but it's also possible that they've both changed too much for that relationship to work again.
