Gail

Gail is an angel of the class of cherubs, called by humans as cupids.

History
Metatron said to Castiel that the second trial required to close de Gates of Heaven was obtain the bow of a Cupid. Metatron heard the "angel radio" and learned that Dwight Charles - a bar tender - would be shot by a Cupid's arrow. The two angels start watching Dwight, but Naomi and two other angels arrive and she takes Metatron with her. Without Metatron, Castiel turns to Dean for help. They continue watching Dwight until a deliver woman arrive at the bar. Thinking she will be the one by whom Dwight falls in love, Dean and Castiel were surprised when they realised the woman was the cupid, because she made Dwight and his regular customer Rod to fall in love.

Outside the bar, Dean and Castiel face her. Castiel wanted to take her bow by force, but Dean convinced him to talk with her first. The two tell the Cupid they need her bow to fix the things in Heaven and then she agrees to help them, saying how chaotic Heaven was, and extends her hand, where appeared her bow as a mark.
