raising second pair flop vs bb raiser+turn problem,

pacific 2/4$ full ring:
hero is mp2,bb new to the table raised pf once in 4 hands.
hero calls 66 mp2 after 2 post dead, but calls,bb raises, 1 dead folds, 1 calls, hero calls,but folds.
flop: Tc 5d 2s
bb bets, dead folds, hero raises, bb reraises, hero calls
figured he leads with pairs and at, any thoughts on the flop raise?
turn: Td
bb checks, hero bets, bb raises, hero calls
thoughts on the bet+call? (assume behind when he raises though he might ch/r fl draw?)
