She is baking cupcakes when she is hexed by Maggie. Jenny finds hearts in the cupcakes and soon chokes on blood. Luckily Sam and Dean burst in and find the hex coin and destroy it. Sam and Dean inquire about the story that Don slept with her, but Jenny shoots it down. Sam and Dean later tell her to leave town for a bit due to her life being in danger.
The brothers are intimated about a possible danger to her by Crowley. The brothers enter her house and after a little searching, find her burnt in her own oven.
