Two pairs oop on turn completing flush in minraised pot

[Yentz]

Cryptologic £200 ($400)

4handed, £200 eff stacks
PF:
I bet 8£ in the CO with Q [img]/images/graemlins/heart.gif[/img] T[img]/images/graemlins/heart.gif[/img]
BTN calls , BB calls

Both are Tags, BTN is a good agressive player and BB is a bit weaker. I am playing aound 20/16, aggro but not crazy.

Flop (£25) 5[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/diamond.gif[/img] 3[img]/images/graemlins/heart.gif[/img]
BB checks, I bet £18, BTN minraise to £36, BB folds

I put BTN on QT+, diamonds and sometimes air/really weak draws. I decide to just call.

Turn (£97) T [img]/images/graemlins/diamond.gif[/img] Giving me top two and completing the flushdraw out there.

This may be a trivial spot, but yet I got confused. How would you gentlemen proceed?
