Tim starts a Tumblr account and posts ‘incorrect quotes’ for all the bats, only they’re not incorrect they’re all actual conversations/sentences they’ve had, and he gains a huge following super quick because every line is pure gold. Barbara is the first to find out and agrees to help keep the secret, then it’s Stephanie who either gains access to the account or starts writing fanfic abt the batfam that includes all these details that line up a bit too perfectly with the truth because it’s hilarious, then Duke who thinks it’s genius and either still makes them buy his silence or starts drafting posts for Tim that he said with/to civilians and/or alone on patrol. Then Dick finds out because one of the Titans shows him this funny blog they found and he recognises almost every post, so he starts looking into it just as Tim starts posting Young Justice and Teen Titans ‘incorrect’ quotes too, and they have to blackmail him into silence.
