"My father's inspiration came from believe it or not another Multiverse that he stumbled upon.. The heroes, the speedsters, and the Allen family tree he despised and fought were much different.... But the Thaddeus Thawne he based me off of was a brainwashed teenager that knew only hate, avarice and obsession. Someone so broken they ran away from redemption right into further manipulation and velocity nine use. He killed The Flash, not Barry but his own twin.. After that he was given a fate worse than death.. When he was freed, he was even worse off, just like anybody would be if they were stuck staring at everything they couldn't be without a chance to scream.  By then he was beyond reason, beyond sanity, someone who would and had killed children out of sadism...  And had to be put down, dying alone.." 

" Think of me as the echo..the rip-off my father made from him.. I had the chances he never did, I was saved... I wish the same could have happened for him... But I won't mourn for him, I will never become him.. I saw him in the Speed Force, and I beat him..  I know I'm not him, I'm better.  No one can ever compare me to him."
