The Onion Knight wasn't quite sure what was going on. He understood that something was happening but didn't know Marlene quite well enough to understand what.

After a few seconds, and trying to remember whether he actually had a handkerchief (he didn't, of course) he held out the edge of his cloak. "Look, wipe your eyes. Just don't blow your nose on it or anything."
