ABC’s Private Practice isn’t done with Grant Show yet. Not by a stretch.

Though the Melrose Place alum will be popping up on the January 16 season premiere of HBO’s Big Love, it turns out he still has some matters to tend to on ABC’s Thursday-night drama — and those matters could be rather… grave.

This much we can reveal: Show will resurface in this season’s 14th episode, airing February 10, when the presence of Addison’s bad boy brother, Archer, becomes a bit mandatory. Show previously logged six visits to Private Practice, plus one crossover to Grey’s Anatomy.
