Sans/Reader is so ungodly prevelant that I have 7 different variations of it blocked an it still manages to get past.
this is an unpopular opinion, but i think that the dceu is setting up joker and harley to be more of an equal standing. like who knows what they'll do with them. not saying it's not healthy (he does manipulate her in the beginning) but like joker and harley, especially considering the arkham games, are a prevelent duo so it's gonna be more present in future movies. like i'm hoping for ivy to show up and do some flirting with harls, but j and h are more iconic
