Line check vs. a Loose/Passive

[Reckless1der]

I haven’t been at table long but noticed villain has open limped or called to see every flop so far. Two notable hands I observed out of the first 5 or 6 is he once called a 3-bet in the SB with Q2s, he also once flopped 2-pair and only called 3 straight donks all the way to the showdown.
