Coming to a Head
Donna, late season 5 (but pre-No Exit), 100 words.
One of these days, she'll do something. She's going to go into his office and hand him her resignation, or kiss him senseless, or both.
But she can't go on much longer like this, thinking maybe he feels this way too, otherwise why would he tease her about that NASA woman?
It's been years now that she's felt like this, but it's getting worse and she needs a change, she needs to change, she needs to feel alive again.
One day soon, she's going to resign and leave, or she's going to kiss him. And she has no idea which.
