Wellard's doing perfectly well, standing up to a bit of teasing. Archie's method of dealing with that sort of poking has always been to simply grin and not deny any of it. It takes the wind out of the teaser's sails. Of course, there have been the times where he just turns red and sputters. That happens just as often as the other.

As for Jack, he can tell a hawk from a handsaw.
