Eric had never thought of himself as a gentleman or some sort of knight in a shining armour.
No!
He was a man that would do whatever it took in order to make sure that he won, or that his plans proceeded smoothly without any issues.
He had no regrets nor qualms regarding his actions, and his next action perfectly demonstrated that.
Releasing a useless newly created clone, he immediately 'threw' it towards the rapier of the Proud Charming Dragon who used it as a target of sparing.
After all, this clone wasn't even a sparing target, as it was too weak. But the poor Proud Charming Dragon couldn't believe his instincts and calculations.
Why would Eric bother throwing useless trash towards him, when it wouldn't even risk his life.
It didn't make sense!
