That's one of the deleted scenes:

hoDS: Scene #193 - Stokes (to Willie): 'For God's sakes man,
get hold of yourself and try to make some sense!!!
It takes place outside the Collinsport Inn and is only alluded to as the film stands. But during the scene Willie tells Stokes that Barnabas is going to do to Maggie what he did to Carolyn (even though at that point in the film Barnabas has no intention of doing so because he's working toward being cured).
Tomorrow's installment in that slideshow is also from Scene #193.
