NL100 - I cant think of one singe hand that would do this... HELP!

[K䲰䮥n]

Villain is a TAG reg. She limps SCs and low PPs UTG. She knows how to protect her hand. The only hand that would do this on the flop is QT but that's really not within her limp-call range. Shorty's insane. God damnit.

Seat 1: Reg ( $100 )
Seat 3: Hero ( $107.80 )
Seat 5: Dude ( $125.30 )
Seat 6: Dude ( $16.90 )
Seat 8: Dude ( $99 )
Seat 10: Shorty ( $20.20 )
Dude posts Small Blind $0.50
Shorty posts Big Blind $1

this doesnt strike me as so worrisome; on this board i would think a tag reg's range is much more weighted to draw/pair+Draw type hands than made straights or a set given the way its played out

prob has 89/8T/9T/TJ/JQ
flat call flop, if checked to, bet/fold turn for 70% psb ($40)
