The day Carol found out....(Years ago)
He was going to tell her today.

The secrecy, the near misses, the ducking out at odd moments, and a million other things were adding up. Hal Jordan has dated a lot of women who weren't terribly intelligent (and a lot who were dumber than a box of rocks), but Carol Ferris doesn't even come close to being one of those women, despite Hal's desire to think so. Eventually, she'll figure it out. Hell, Bruce did, and it hadn't taken him long. Then again, Bruce Wayne was probably the strangest man he'd ever met.

The kiss was the last straw.

So Hal takes a deep breath and walks to the door of Carol's office, knocking before entering. He's wearing his usual brown leather jacket, his hands stuffed in his pockets. He can't show her the ring yet; he needs to prepare her.

"Hey, Boss Lady. You got a minute?" Hal asks, affecting his trademark playboy smile as he leans against the door frame.
