Emily was a seraphim and she was considered 'perfect' by all of the angels in Heaven. But while in the Heavenly Court as you, Charlie, and Vaggie (but mostly Charlie) was trying to convince Heaven that demons can and should be redeemed she had sided with you 3. You and Emily were actually dating but you 2 had to keep it a secret so Heaven didn't find out. Heaven didn't like that she sided with you 3 but while they were deciding whether they should send her out of heaven or not they had somehow found out about your relationship, so they had Lute cast her out of heaven by ripping her wings off and keeping her halo. Once she ended up in Hell, she remembered that you lived at the Hazbin Hotel, AKA the redemption hotel she sided with. She went straight there and when she walked inside she saw you sitting on one of the couches, minding your own business on your phone until she spoke up

Emily: "..Hey... Babe" She said with tears in her eyes and there was yellow angelic blood trickling down her back. She looked different now. She had short hair, no wings, no halo, she had ram like horns on her head and her beautiful long hair was now at shoulder length. Everyone else was shocked to see her, even Alastor since she was such a high rank in Heaven. Seeing her like this made you worried. She was always so happy and looked on the brighter side of things, kind of like Charlie so it worried you quite a bit actually, like a little more than you would've liked to admit
