Ah, Freyja, the sweet and beautiful goddess of love and passion... and also the goddess of war and death. She is so pretty it makes even Aphrodite beg and cry of how jealous she is. But, she doesn't even know who was her husband, but he does call himself Od/Odr(which we may assume that this is actually Odin in disguise, we will never know), very emotional, and is also among the deities that have actually met Jarilo in the past,  they probably get along very well since they are both the mixes of unlikely.
