A few days after Mary's funerals. Dean, Sam and Castiel worked on a case in Ohio. What seem at first like a typical vampires nest turn out to more complicated.
''-I'm going undercover.'' said Dean.
Sam as well as concerned by his brother's safety, agreed to Dean's decision. ''-It's the only way. Dean gonna make it to the nest and then he call us right away and we're coming to killed them all. It's a good plan, don't worry it all gonna be alright.'' Cas on the other hand refused to put Dean at risk. ''No way, since when one of our plan actually worked. It's not safe, we are talking about at least twelve nasty vampires who slotted a entire bar last week. You're not going, I won't let you.''
Despite Castiel's arguments, Dean and Sam agreed to let Dean going undercover to join the nest they were hunting.
Sam went to a shop to buy some stuff they needed and left Dean and Cas at the motel.
Cas was still concerned by the mission which could gone wrong in so many different ways. ''-It's too dangerous...
-Nothing gonna happened Cas, we do the job like we used to and I promise we will be home before you realized it.
-I hope you're right''
They heard the car outside, meaning that Sam was back.
Cas looked at Dean: ''-Be safe out there...
-I will
-It's just...after Mary's death... I can't loose you too...''
Dean step forward, to be closer to Cas. In a way that the angel could feel Dean's breath on his skin. ''-You won't.''
