Hearing the same dialogue between Varric and Solas (Spoilers)

I have heard Solas as Varric about battleing Corypheus before about 100 times now, and it's getting really annoying.  I don't know why this particular dialogue keeps playing.  I don't hear and other banter between my companions now as this is always the dialogue that plays.  Is there a way to fix this?  Or will I have to replace one of my companions to make it stop?
