Per TVGuide.com, Collins will appear in Episode 14 as Dylan, a man that both Bridget and Siobhan have a past with and who is partly responsible for the wedge between them.

Collins’ fan favorite character on Supernatural was seemingly killed off in this season’s second episode, but showrunner Sera Gamble has said she hopes to bring back the actor in some form.
