We all know Deadpool would treat Harley like a goddess. Adding to the fact he would stalk her and watch her sleep. Pretty much like Deadpool's current GF or EX. Sorry lost track if there still together.
I'm not all that keen on Harley's outfit, not so much the fact that I tend to feel annoyed with these kinds of outfits, which among other things have been done so many times already, but because it's kinda out of character for Harley, and honestly looks really uncomfortable.
However, there's still an intensity about the two that I like. And yet there's still hints about the more light-hearted parts of the two with the amusing key chains, the grenades with "boom", and Harley's headband with Deadpool's logo on it.
Oddly, seeing them so overly decked out in weapons, Harley in particular, doesn't bother me. Honestly, I almost feel bad for whoever pissed them off so much that they went from wacky crazy to serious, scary, crazy.
