Open to General Fighting of Minions etc
Even though Peter had argued due to Jake's age, Sarah had stuck to her (metaphorical) guns and argued right back about Jake's skill. She had won the fight, but since she was the one who had his back, Jake had to do as she instructed. Just under not getting himself killed and keeping back from the main fight, was looking out for their allies.
So when a minion had spotted Fred's attack, and started to turn that way, Jake had a dish in hand and sent the plate flying. The minion hit the dirt at Fred's feet, the plate imbedded in his chest. Jake made a mental note to go back for the Riza after the fight; he only had a limited number of the plates, and he didn't think he would be able to find more here.
Rather than stand alone on the battlefield, the boy drew two more plates, one in each hand, and moved closer to Fred. "Hi," he said, once he was within hearing range. "Maybe we could watch each other's backs?"
