What dose luis plan to do to get back Erik and Arthur, and who is going to help him

There is going to be a memorial ceremony for Mike Costello. Paul goes along glumly. Soon after the award ceremony begins, Paul sees Victor and Tino coming into the auditorium. He doesn’t understand what they’re doing there. He’s terrified as he watches them move toward the stage. He realizes that they’re there to avenge Luis. They’re waiting for Erik to go up on stage, and nobody else seems to notice them.

As Erik steps up on the stage, Tino walks up to him and kicks him in the gut. Then he hits him in the face and says that it’s for his brother, Luis. Victor jumps on Arthur and starts beating him up. The auditorium erupts in chaos. Coach Warner jumps on Tino while Victor runs off to the back exit. The alarm goes off as he goes through the fire doors.
