I don't know what Carey was thinking with that Sinister thing. Sinister does not have the feats to be in any kind of top 5 TP list. Was he basing it on the fact that Siniister stole Xavier's genetic potential or whatnot from back in the day? I can't really remember. Isn't that why Miss Sinister was a strong TP cause she had Xavier's genome? I'm not really sure cause I started checking out a bit during that time.
