The name blake has an intersting meaning. (or atleas thats what some name site says) Dark; dark-haired. Can also mean the reverse: 'fair; pale.'
so it has a bigger meaning than a balck hole pun. (but that pun is still epic)
He in a sense isnt pure evil in the end so he goes from dark, to fair XD
Doesn't he change his name to Wyatt at the end. which would be White hole ...?
