I love how Cap looks mildly apologetic and conciliatory in that panel, even though he's basically chewing Johnny out. 'Errm,,, bad news, I'm afraid, son. See, due to your, well, meddling, the Earth has lost a valuable and irreplaceable asset - we assume irreplaceable, anyway - and, yes, it's all your fault. Sorry. But hey, it's not THAT bad! Maybe one day you'll do something EVEN WORSE, and then this will seem like nothing! Buck up, soldier!'
