Tony & Darcy
Darcy wasn't responding with playful sarcasm to babbling OR about cats (which were still ginormously popular on the internet). Wow, Tony thought, something was seriously off with her. Almost like she might suspect something was up, which it was, since he was being uncharacteristically quiet.
She turned out fabulous without him. It was probably a good thing she was nowhere near him when she was growing up. He knew given his tinkering habits that he wasn't exactly dad of the year, even if he and Morgan kept each other entertained with a mutual love of cartoons with robots and animated explosions. He still worried about messing up Morgan somehow, and didn't want to think too long about what she was going through in that other universe after he died. Other than he'd still do again here, if he had to. Not even a second thought.
"....I already screwed up, years ago," Tony grumbled, face scrunched up miserably. He knew he was going to have to bite the bullet like Rhodey was saying, but was still reluctant to tell her at a big New Years Eve party, ruining everything and potentially causing a scene that any covert press reps would be all over like glue. "I'm being weird because I've got something life changingly important to say. The middle of a dance floor isn't a great place to drop bad news. I don't want you to get mad or freak out, soooo...maybe we can pencil this in on your schedule. When's good for you? I got a ten o'clock open on Thursday. You free?"
