Romanced Emmrich Combat Dialogue Never Triggers

100+ hours in and I have not heard a single line of Emmrich's romance specific dialogue in combat. He only ever says the non-romanced lines (ex. "a fine hit Rook!" as opposed to "a fine hit darling!"). He is always in my party with a rotating second companion. I have no problem triggering romance banter otherwise. I wondered if this was because I was playing in Storyteller mode, but I've experimented with changing my settings to no avail.
