But... all the antagonistic history between them! Two men who grew up together, who know each other like brothers... their fumbling adolescent experimentation in the Pemberley woods... then Wickham starts playing the rake, drinking, gambling... Darcy is the responsible one, tells him not to be a bloody idiot... they fight, they have make-up sex, they fight some more... Darcy is torn, but can't go on dealing with Wickham's increasing screwedupness... breaks up with him... then in a fit of wossname, Wickham tries to get back at him by eloping with his sister... and then when they see each other in the street in Meryton... tell me that isn't the horrified "omg it's my ex!" moment from hell?

But Brandon? Brandon and Darcy? Oh boy, wouldn't they have some notes to compare! There'd be a definite sympathy there, if Darcy could put his pride aside and bring himself to explain the whole Wickham saga in the first place, of course. Hrm actually, that could be rather interesting... I wonder what Darcy would think of Brandon's story, whether it would make him like Brandon better or scorn him? Either way, definite potential.
