A sick wombat and a caring diagnostician

When Chase woke up he knew he was sick but went to work anyway. It doesn't go well and soon he finds himself in the bathroom hugging the toilet. The last thing he needs with a stomach bug is his boss. Or so he thinks. But House turns out to be surprisingly nice, taking care of his sick duckling with the help of Wilson. And although Chase has pretty much the worst day of his life, House is there and actually makes all this a little more bearable. In the process House learns that he would do pretty much everything for his little wombat (or de facto son :)). And although Wilson could never imagine himself co-parenting one of House's sick ducklings, here he is.
Set somewhere in season six. Focuses on House & Chase father-son-relationship and House & Wilson friendship.
