Early hand from Multi Table Tournament

[Runner Runner]

Here is a hand I played that I feel I screwed up a bit. This is about 45 minutes into the final day of a two day tournament where the first day was a qualifier to the second. Everyone started with T15,000 on the second day. Villain seems to be a reasonable player who is a bit too loose and aggressive, he has T30,000, the rest of us have about what we started with.

Blinds are 100-200

Folded to Villain who raises to T600, I call with AJo, LP calls, SB calls, BB calls.

Pot T3000

Flop K J 8 (rainbow)

Villain bets T600, all call.

Turn 6, checked around.

River 2, Villain bets T800, I think for a bit, say "I just call" and call, everyone else folds.

Thoughts on any streets appreciated.
