Should I fold here?

[oxymoron]

This is an early hand from a $20+2 two table tournament. I have no reads on anyone. I hesitated to call because it was such a high raise but my thinking was he has JJ or QQ and is afraid to lose so if I flop a pair I'm good. I didn't like calling thought because if I didn't flop a pair I had to fold. I feel my action after the flop was fine as I not only had TPTK but a draw to the nut flush. Thoughtson this preflop?
