Numb3rs Anti-drabble meme

You all know how a meme works right?

You leave a prompt and the journal's author leaves you fic. Well I have 7 Don/Ian drabbles, with no prompts, so I'm flinging them open to claiming. Pick a drabble and leave me the prompt you would have left to get said fic.
Only one prompt per person.
Enjoy.
