Walter plays Cappie (sic), desk clerk of the fleabag Mokupuni Hotel where Driscoll, a hitman who seriously wounded Magnum,
is hiding out. We first see Cappie sorting mail and giving Driscoll a phone to use.
After Cappie passes word to Magnum via Icepick, the show's resident criminal underworld source,
that Driscoll is planning to flee to the mainland, Cappie is
brutally murdered by Driscoll and his body dumped in an abandoned building.
