They are actually concerned. It's just that they were recovering from carbon monoxide poisoning. They were so compromised that the two adults were fighting off the final, paralytic stage of monoxide poisoning. That kind of injury literally kills brain cells.

@PupcakesDogCare I don't think you properly grasp what they are experiencing... they aren't crying and whining because it's hard - they are crying and whining because they are legitimately on deaths door (the last stage is paralysis which finally ends the person). Look yeah they are messed up and imperfect and did messed up stuff... but let's not overlook the fact that these guys almost succumbed to carbon monoxide poisoning. It literally kills brain cells as it displaces oxygen into the brain like a stroke would - but you would be experiencing toxic-induced atrophy.
