Weird villain line

[CruS]

Villain is 30/9 over big sample,
does definitely not 3bet light.
He is somewhat aggressive postflop..

What do you think of this line? My thought process is in blue:

Full Tilt No-Limit Hold'em, $0.25 BB (6 handed) Full Tilt Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

Button ($25.90)
SB ($10.10)
BB ($22.35)
UTG ($21.60)
MP ($23.95)
Hero ($25.55)

Preflop: Hero is CO with J[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/club.gif[/img].
<font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises to $0.85</font>, <font color="#666666">2 folds</font>, <font color="#CC3333">BB raises to $1.7</font>, Hero calls $0.60.

Flop: ($3.25) Q[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/diamond.gif[/img], 8[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets $1.5</font>, Hero calls $1.50.
<font color="blue">
Cheap bet, I sense some weakness but I rather just peel one and see what the turn brings.</font>

Turn: ($6.25) 6[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets $2</font>, Hero calls $2.
<font color="blue">
Another cheap bet, I suspect AK or a scared AA because of the straight / set possibilities.
</font>
River: ($10.25) 7[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets $6</font>

<font color="blue">
Wait a second, this does not add up, he bets the flop like he is either very strong, QQ-AA or very weak AK etc.
His 3betting range definitely does not like that turn and definitely not that river, and now all the sudden he bets strong? more than 1/2 pot when he should be scared of the board even w/ QQ..</font>

Call?

Anyways how is the rest of my line when I have the read that I have?

Thanks
