Daemon, at the time, wasn't even sure why he had done it... but he regretted it now. How could he not? His wife's dragon was dead... because of him.
He felt like a spoiled teenager all of the sudden, none of it felt worth it as he saw the scene in front of him; you dragon's dead body curled around your own on the ground after he'd killed it.
Why hadn't he stopped when he heard both Caraxes and Syrax cry out? When one hadn't even been hurt? They didn't deserve it and Daemon was a fool. Daemon could feel Caraxes' distress and made him feel even worse. His dragon was his best friend but now... He'd be depressed and it was Daemon's fault.
He landed his dragon and then moved closer to your body, Syrax' body had marks everywhere and she had managed to get Caraxes a few times, but the war experience really got her. He had decided that he was done with you, you had felt the same and instead of him continuing to help you claim the throne... he decided that he wanted it for himself until this happened. He didn't want it anymore, he regretted everything. This wasn't what he wanted anymore. You had almost died, and your dragon did die. One he'd known since you were a little baby.
He was silent as he climbed down and walked over to your knocked out body, he leaned down to stroke your messy hair in silence. Even knocked out like this, you looked so tired. Any ambitious that he had, was gone. Need for the throne? Gone. He just wanted you to be safe again.
He sat on the ground besides you and didn't move for some time, waiting for you to wake up, he wanted to know you'd be okay.
Then you woke up; you bolted up breathing heavy like you'd had a nightmare and his heart pang with guilt. "What?" You spoke to yourself before you saw him and backed up, hitting Syrax' dead body in the process, "Daemon." You said before turning to Syrax, you could see the dragon wasn't moving. "Syrax?" Your eyes widened, your dragon dead and you couldn't help the tears.
Daemon stayed crouched in front of you. "Let me help you..." he begged.
