Ace nine suited from CO

[ATM]

Just wondering what could my opponent have here it just seemed really weird to me. Villain is SB who just a minute a go min raised to .20 from 1st position with ace six suited and was re raised to .80. Villain calls hits a six high flop. Original raiser pot bets and she calls hits an ace for 2 pair. Just so you know what kind of player this person is. Might give people a better understanding of what her re raise and min bet means
Full Tilt 6 max .5/.10
5 people at table we all have about $10
One limper behind me I raise to 0.40 from CO with a /images/graemlins/heart.gif 9 /images/graemlins/heart.gif
Button folds SB re raises to .70, limper calls the .70 i call the .30 flop comes 5 /images/graemlins/club.gif 8 /images/graemlins/heart.gif 3 /images/graemlins/club.gif
SB bets .10 and limper calls i fold.
what does this bet mean and what is the person most likely to have

getting great odds here. two over cards, backdoor wheel, backdoor flush draw.

Punish them for the donk min bet giving you 23:1 pot odds. If turn doesn't help you then check/fold.
