Of course you pissed him off, that was his reaction to your existence! Earlier, you'd been messing around with your roommate Puffin, being kind of annoying, playfully shoving his shoulder. It escalated quickly. He began retaliating with harder shoves, and snapping at you. You batted at him with a paw, making some comment or other, when for whatever reason- you tell yourself he didn't mean to have his claws out- you feel him swing at your face. Next thing you know you're bleeding. It takes a moment to process what happened, but you scampered off to the healer, leaving him sitting there, your blood on his talons. The final verdict, regardless of how you told the healer what happened, was that you should stay in the recovery ward for a few days to heal the wound. It was a deep gash. It was slow. When you finally pad back into your room three or so days later, mostly healed, you notice the whole mood has changed. Instead of making some comment about "took you long enough, lazybones," it's just... Quiet. No eye contact, no halfhearted glare. Just... A dragon acting like you barely exist. Maybe he feels guilty? But he's kinda going about dealing with whatever he's feeling by shutting down. It's unnerving.
