Also, if anyone could explain the jumping into the acid vat scene...like they jump in, does not seem to hurt them at all, then they start making out while there is paint in there. Like what was happening in that whole scene?

Basically it is an allusion to Joker's origin story. The vat at Ace Chemicals is how he originally went insane (Burton's 1989 Batman followed this origin).

Harley was in love with him and jumped in so that she could be like him.
