NLCASH - Strange line from both hero and villain

[xSCWx]

Haven't been playing him very long but I can tell that he isn't very good. He limps from his button about 60% of the time, I'm not sure if he has raised preflop at all prior to this hand.

His line to me looks like air or a set to me, but I felt compelled to reraise against a strange naked ace line.

I'm interested in thoughts on each street with the river raise in particular.
