"You could've mentioned you're allergic at some point"

All Chase knew was that he needed to get air. Now and fast.
“House”, he managed to wheeze and involuntarily started to cough, “I- I cn’t…House!”
He realized that he was shaking now, his heart beating so fast he could feel it in his entire body. Tears formed in his eyes, but he could still see House jumping up as he realized his struggle for air. Putting an arm on his shoulder House tried to get is attention by turning Chase to look at him.
Or: House learns the hard way that Chase is allergic to strawberries and has to make sure his little wombat doesn’t die from an anaphylactic shock.
Set somewhere in season three, developing father-son-relationship between House & Chase
