Will Joe Carroll (James Purefoy) ever run out of followers on Fox's The Following?

Not any time soon, apparently. The show has added newcomer Mackenzie Marsh in a recurring guest role as Tilda, a woman with anger issues (naturally) who forms an attachment to the escaped serial killer, has learned exclusively.

Though she's feisty on the outside, Tilda also has a deep sense of insecurity stemming from years of ridicule, as well as a soft romantic side that has yet to be uncovered. And fans of the show know that Joe Carroll will have no problem using both of those traits to his full advantage — though we're guessing Emma (Valorie Curry) may take less of a shine to the newcomer.

What do you think of the new follower?

The Following airs Mondays at 9/8c on Fox.
