You know what would've been cool? If the templar that your Inquisitor could potentially have a crush on when she was in the Circle actually showed up, either working for the Inquisition or in one of the cutscenes regarding the Templars (as a red templar or a normal one), just to see what Cullen's reaction to it would've been, lol.
Of course, that would be impossible to do since your Inquisitor's taste in men/women/race/whatever is down to your own individual tastes etc, but it would have been interesting. Wouldn't mind seeing Cullen get jealous like the companions did in DA2.
