As far as dialog goes, the whole scene seems like a cheap attempt at deus-ex-machina which I try to stay away from. Also, somehow it seems that I would be able to justify the reason for the unfaithfulness on Bier's part. The whole Nazi thing, the head banging, and now it would seem the scientifically proven CTE discovery (which describes Bier to a cue). In the attempt to try to turn the tables by having the high school gf using the cheating to dump Bier, as opposed to the real reason which would be finding out what kind of guy he really is: forgetful, high strung, borderline sadistic, etc.
I wanted to try to jump back and forth like I did in the previous sequence, but that would've probably resulted in losing my train of thought for this B-story concept which I don't know how far it'll go, but suffice it to say that they jump in Bier's car again and head toward one of the buildings which they vandalized to see whether SHE on TV4 lives there, but really, I guess, where I have to go with this chase is these two pot heads driving to various different houses which only Bier knew was the one where SHE on TV4 lived. Off the top of my head, I am thinking I would like to make this destination on Griswold and Colorado in Eagle Rock because of a scandal I read about murder or something in that area.
