Changes

The relationships between archangels and their vessels can be complex. Holding an archangel is damaging to a human; Raphael's vessel, [[Donnie Finnerman]], was left catatonic after his possession.<ref name="five03" /> Lucifer's continued presence in [[Nick]], an alternate vessel, causes the human's body to break down, as evidenced by burn-like marks on his skin. Lucifer's vessels can be strengthened with demon blood to better survive the ordeal. Despite his contempt for humanity as a whole, Lucifer showed some sympathy toward Nick, and toward Sam, his true vessel. However, as it was later revealed, Lucifer's sympathy towards Nick was simply an act of manipulation as he had orchestrated the murder of Nick's family to get him to say "yes."<ref name="fourteen11" /> Michael, though condescendingly, was willing to explain his position to Dean while occupying his father, and promised not to leave Dean a "drooling mess" like Donnie Finnerman after his service.<ref name="five13">[[5.13 The Song Remains the Same]]</ref> Lucifer also displayed the ability to use [[Castiel]], a lesser angel as his vessel without causing visible damage to the body. However, Castiel is noted by Sam to have a particularly strong vessel<ref name="eleven18">[[11.18 Hell's Angel]]</ref> and Castiel later states that being Lucifer's vessel is in fact slowly burning both it and him out.<ref name="eleven22">[[11.22 We Happy Few]]</ref> In contrast, while housing the [[Apocalypse World]] [[Michael (Apocalypse World)|Michael]] who is far stronger than the Michael from the Winchesters world, Dean was not only able to remain conscious without any apparent ill effects, he was able to retain control of himself and even use some of Michael's powers as per a deal with the archangel. It was only when Michael betrayed their deal that Dean lost control of his body.<ref name="thirteen23" /> The Michael of the Winchesters' world, after escaping from Lucifer's Cage, shares control with his vessel, [[Adam Milligan]]. The two are able to openly converse with each other, with Michael appearing as a duplicate of Adam in the waking world, though only Adam can see him. Adam later explains that he and Michael reached an understanding when they were trapped for all of those years together in Lucifer's Cage during which time they were all each other had. Michael appears to be protective towards Adam, particularly angry with Dean over abandoning Adam in the Cage while he was willing to let Lucifer roam free and the archangel and his vessel even appear to be friends with each other.<ref name="fifteen08" /> After Adam dies with the rest of humanity, Michael is visibly saddened when he informs the Winchesters of this, showing genuine grief over Adam's loss.<ref name="fifteen19" />
