What if he survived?

First of, sorry for grammar mistakes. I plan to fix it when I will have free time.

What if Draal survived with just an injury, met the Merlin, lived in the basement again, etc...... Well, we all wish it... But does we know if he got some trauma from his serving to SkullCrusher? And what if after battle will Merlin heal the Heartstone? Will he be strong enough to live in place that he helped to destroy, even if it wasn't his fault? Does he have a courage to look into his father's eye's? Read and find out.... (Possible idea that Merlin won't heal the Heartstone and Draal will stay in Arcadia)
