Sam and Dean inquire about the story that Don slept with her, but Jenny shoots it down with discomfort. Sam and Dean later tell her to leave town for a bit due to her life being in danger.
The brothers are intimidated 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.
