I didn't exactly get you a card...
J'anna didn't call ahead and it chewed at her as she made her way over to her father's residence.  What if he was hanging out on Mars? What if he and her mom were, uh, busy?  What if (and this was the big one) he was choosing to spend Father's Day with Jenn?  It'd happened once before, a memory that was still too sharp to touch for long in remembering.  She didn't call ahead because it gave her an out.  If J'onn didn't know she was coming she still had a chance to bail out and that was what she most wanted to do.  Everyone was on her to reach out--Tim, Cerdian, Ruth--but not reaching out was more comfortable.  She'd said some awful things and meant them all.  There was no taking them back, but she could just not do this.  She could just go home, drink a pint of half-and-half, and drown her accumulated sorrows with a few dozen boxes of Chocos.  But, by the time she worked up the nerve to flee...she was standing on J'onn J'onnz's doorstep.

"Damnit," she whispered before swallowing hard and knocking.
