Larry tends to blame himself for things that go wrong at times - because they really do go wrong because of him, but still - but he's not one to repress feelings for so long, that's how he rolls.

Right now, he doesn't feel guilty of anything, BUT he will try to help all his friends who end up sick. So in the end, he might end up coming down with a bit of the "flu". Nothing more serious than that. Unless someone tells him to please take all necessary precautions and make sure he doesn't touch anything. Please.
