There's chastised, and then there's absolutely gutted with a side of heaping guilt. Darcy looks away, down somewhere around her feet as she just lets his words sink in. Coulson is right, of course, because he's got that annoying habit that no one can shake him out of.

And she very much doesn't want anyone to die, which is entirely the problem and one that she doesn't want to think about how he knows. Loki, by all rights, deserves death for attempted genocide among other things including a hefty collateral damage toll. She's not stupid, nor blind to that - except for when she apparently is.

"I'm sorry. I don't..." Darcy takes a deep breath and looks back up at him, her brain finally understanding the last sentence. "So I'm still... you're not firing me?"

God, she doesn't want to leave this job. She loves it, loves the people she works with and the excitement and being able to help in a way she didn't think she'd ever be able to. It's better than politics and Darcy never thought she'd say that about anything.
