Kilmartin, who is a writer on Conan, has been live-tweeting from her father's bedside, sharing her family's experiences at a heartbreaking time.
Kilmartin has caught the attention of Twitter the past few days.
Other times, she addresses the difficulty her family is going through with a spark of humor.
And sometimes, she doesn't need to say anything at all.
