alternate Gabriel

(Requested) This so-called Gabriel is a pale-skinned, blond-haired archangel seen wearing white robes. When showing their true appearance their eyes grow in size and their mouth is stretched into a smile. This alternate has some slight differences from true Archangel Gabriel, such as a longer face and hair and a lack of wings. (story) you went in a abandoned church and saw him, you turn to leave but the windows and doors are locked shut with the windows being boarded it up now. what will you do?
