Looking for a story

I am looking for a story where Spencer gets hit by a car while saving Henry. I think it was about the time that Emily returned to the BAU. If I remember correctly they were at a party where the BAU and Spencer fight and after the fight Spencer leaves and as he leaves Henry runs into the road and Spencer catches him and throws him to the rest of the gang and he gets hit by the car. The story was either on fanfiction.net or archiveofourown.org.

Thanks a lot!!!
