Dimitri had thrown up and then bolted when Darcy cornered him in the infirmary. SecUnit isn't cornered. And it hasn't left yet.

"I don't know." Hard, painful words Dimitri's adding to his vocabulary. He shrugs off the blanket, tries his best to fold it, and sets it down in front of them. SecUnit can pick it up, if it wants. "But I have to try. I'm here, unless and until you want me to leave."

They have time. They have nothing but time. Dimitri can sit here, quiet and still, until that trapped, snarling animal realizes he's not a threat.
