Cedric sees the vomit and winces. Yes, that's a reasonable reaction. He's glad Howard's there, and alive, but look at what almost happened to them. Without the wand, he'd still be dying.

It's a sickening thought, though the only visible sign of Cedric's fear is shaking.

He crawls closer to Howard's side and flicks his wand again, clearing the vomit. Letting it linger will simply make them both sick again.

"Breathe. It didn't happen. We're getting out of here." Cedric kneels beside his friend, whispering the words of comfort. While he's at it, he looks Howard over for injuries. They shouldn't be too bad, right?
