Riff was laid up in a hospital bed after his most recent rumble. He’s hot headed and loses his temper easily so it was enviable something bad would happen.

You got word from his new girl Graziella that he got stabbed by a shark. He dumped you for her since she has a tendency to date whoever the Jet’s leader is. Tony got arrested so Riff stepped up and she took Riff from you

Once you enter you see the room filled with the Jets as they tearfully stare at Riff on the hospital bed
