Ren doesn't comment on their ages: Talcott's not wrong. Ren's seem teenagers be just as tough as adults, but still... they had middle schoolers here. Mitsuru was 11. Him, Talcott, Ichigo and a few others were the eldest. The only protection the younger ones had- cuz like hell they could depend on the adults.

Still, Tal's words fill him with dread. "Your home sounds... intense." The sad look on his face says plenty.
