Harley Quinn in the new Suicide Squad trailer.
Batman in the new Suicide Squad trailer

LOOK THIS IS WHAT I’M TALKING ABOUT
is this the face and mannerisms of someone who just pushed someone into a chemical vat? nah man this is the “god damn it you just did what i told you not to do, and my ass is not about to ruin my 200 dollar jacket to pull you out of this mess…” look right before he jumps in to take someone out of the chemical vat
so from what i can put together, harley’s jumping into the vat of chemical waste herself and joker’s like ‘what iN THE HELL’ and jumping in after her to pull her crazy ass out of there.
