3rd street - hero MUST raise.

4th street - hero should fold, pot is too small BECAUSE YOU DIDNT RAISE!

But ignoring pot size I think 5th street is a check, villain raised on third street into that field, you can bet as a heavy favorite that he has a 4 card hand made and didn't pair the 6 on 4th street. I have to admit its might close to a bet, but I think checking is slightly better.
