Part four of five opens with us seeing Shrubby curse Harley for wrecking up the club after he vouched for her. He also calls her a 'skirt.' Isn't that like, 20's Italian mafia speak coming out of the mouth of a 70's themed disco vegetable? Plus, she isn't even wearing a skirt which makes it a bit stupid to refer to a female as a certain part of clothing if she doesn't normally wear that style.
Anyway, Batman and Nightwing are waiting in Shrubby's apartment because of course they are and the whole thing sounds like a bad domestic violence screenplay
Batman: That's quite a shiner there, Dougie. Been in a fight?
Shrubby: I walked into a door.
While they're talking, Shrubby just straight up walks over to the window, opens it up and tumbles out. Does Nightwing make a habit of this happening? Of course, Batman's put a tracer on him and they're going to follow him straight to Harley Quinn.
Side note, Shrubby's feet just don't look big enough to support him standing let alone jumping out of a few storeys and running off. What is he, a six year old ballerina?
How much time has passed here? I assumed this was all occurring immediately after Harley flipped out for no real reason but in this time frame Batman and Nightwing have already heard the news about the fight and have in their own words - talked to literally everyone - and now Poison Ivy is apparently on a weird tutorial date with the Floronic Man.
