So team free will is all reunited in the bunker (zeke is back to his original vessel) and all is well. As the hunters and the fallen angels go about their day, Zeke and Cas like to speak to each other in their native language...however, Dean and Sam find it very frustrating and annoying!
idc how you want them to deal with the situation, maybe dean and sam try to snag bits of the convo and translate it to no avail or maybe they confront the angels about it. It's up to you! :)
