2 Pair - Berate me for ignoring a read

[22pajo]

Limit: $0.50/$1
8 players

Pre-flop: (8 players) Hero is CO with Q[img]/images/graemlins/club.gif[/img] T[img]/images/graemlins/heart.gif[/img]
4 folds, <font color="#cc0000">Hero raises</font>, 2 folds, BB calls.

Flop: T[img]/images/graemlins/club.gif[/img] Q[img]/images/graemlins/heart.gif[/img] K[img]/images/graemlins/club.gif[/img] (4.5SB, 2 players)
BB checks, <font color="#cc0000">Hero bets</font>, <font color="#cc0000">BB raises</font>, <font color="#cc0000">Hero 3-bets</font>, <font color="#cc0000">BB caps</font>, Hero calls.
<font color="blue">villain played too many hands and usually passively pre and post flop so his flop c/r lead me to believe he had flopped a made hand but despite the read i bet agressively on the flop. After he caps i'm calling hoping to hit a full house</font>

Turn: 3[img]/images/graemlins/club.gif[/img] (6.25BB, 2 players)
<font color="#cc0000">BB bets</font>, Hero calls.
<font color="blue"> i'm happy enough with the turn call after picking up a FD </font>

River: 8[img]/images/graemlins/heart.gif[/img] (8.25BB, 2 players)
<font color="#cc0000">BB bets</font>, Hero ???

Is the pot big enough to justify a call here with 2 Pair?
Was even the blind steal preflop worth it with QTo?
