Hi, what Tux and Kevin say is decided randomly in this situaton:

			Tux:says_random(_"Hello.",
					_"Hi there, Kevin.")
			Npc:says_random(_"Well, hello again.",
					_"Hello hello.",
					_"Welcome back.")

but I agree, it's a bit odd to say "Welcome back" when meeting for the first
time. I'll fix that.

Thanks for the report :)
