Hannibal had awoken to Will covered in blood and panicked. It had been a struggle to remain calm and get poor Will to the hospital; the temptation was strong to try and fix whatever wounds he had himself, but now was not a time to be possessive or jealous.
The wound to his shoulder was clean, thankfully, as was the one on his forehead. But he'd have some nasty scars to add to his collection.
Now he sits next to Will's hospital bed, watching. He should have slept while he was in surgery, but he wasn't able to. He'll sleep when he knows Will is safe.
