AA on the bubble PF min re-raise

[stinkysam]

10+1 re-buy
17 players remain, 10 cash

Villan has been sitting to my right since the 1st hand of the tourn. He is extremely tight and for the most part passive.
Since we are only 7 away from the money many hands fold to blinds-most are 2 or 3 ways max to the flop

Blinds 600/1200
Hero is in CO 33,000 chips currently running 4th
Villan is 1 seat to my right approx 13,500 chips

Hero has AA

1 call
Villan raises to 2400
Hero reraises to 3600
both call

villan checks
hero bets 5000
villan raises all-in for his last 5000

Hero??

5,000 to call a 25000 pot - looks like a call to me.
pf re-raise too weak? figurd the hand was too strong to just take blinds + 1 BB, plus most pots were HU at this point anyway which was why I only min-re-raised. Am I way off here?
