Two stories
The first has Shawn on his motorcycle, he stops, maybe at a red light?, and a group of guys in a car also stop and claim he cut them off or something, then they beat him up and drive away (and possibly steal the motorcycle). Shawn is lying on the side of the road for awhile, then gets to his phone and calls Gus and is pretty confused but manages to lead everyone to where he is. The second has Shawn leaving the Psych office, possibly for a snack, when he gets hit by someone on a skateboard and injured badly and tries to make it back to the office. Thank you for your help!
