GM meta note: that looks like a five second speech or thereabouts to me. Remember that GURPS combat is in one second turns; the fight is only three seconds old. As in reality, lethal violence is often stunningly sudden.
I’m not enough of a pedant to enforce this sort of thing, but if the fighters want extra roleplaying kudos they should get in a few more rounds of sword-swinging before reacting to Hawk’s statement.
