We had one drop into a Crota hard raid, our 4 regulars + a random, and then this kid drops in, couldn't have been more than 12. No one claimed him. We let him stay, 3 wipes, then one tried to convince him to shoot the crystal point blank with a rocket, but he ended up catching on. Instead we made him stay in the crystal room on thrall duty. He won't stop talking. 2 of us mute him after he kept talking about how many times he's done normal. The rest of us kill Crota in the next run, kid gets Cryptographic AND Glowhoo... yes "I've ran it a thousand times"... sure, kid... The other guy was cool, up front said he never done hard. Asked the right questions, followed the plan perfectly.
