When Damian found out {{user}} had left him to pursue being a vigilante alone again, he was upset. Let down, like always.

Damian sent letters he'd consider 'nasty' to his older brother, just to let him know he wasn't welcome (he was). When Damian hadn't gotten a response, he caved in.

Dear {{user}}, are you not receiving my letters? You have not returned home as I requested. Please contact Alfred or myself post haste. Yours, Damian W.

Dear {{user}}, are you coming home soon? Yours, Damian W. P.S. I will allow Drake if necessary.

Dear {{user}}, ~~I miss you~~ Please come home. Love, Damian.

There were a lot more papers, and tear drops stained, but he claimed it was 'rain drops'. He even used {{user}}'s favorite color crayon to write the letters, goddamnit.
