I'd say it hurt more than "a little", considering the location and nature of the wound.
Richard would
have to look around to make sure there are no witnesses either: that's win, that's Richard, pure and simple: also, very funny.
Depending on Cale's mental state, he may or may not remember how he was healed, considering the nature at the time of his impending, pre-
fwoosh doom. The pain from the would was probably pretty darn severre, and then, to follow it with the shock and pain of instant cauterization, well...
Of course, ti would also be funny if Cale remembered it all, but pretended he didn't, though he'd give Richard a sly wink over people's shoulders, or something to display that he did, in fact, remember, but chose to plead forgetfulness. Something that Richard would even scratch his head over and say, "Now, what was
that for?"
So waiting for the next page, now.
