He completed, so i wouldnt put him on a strong ace. He could however be on the A4, K4 or similar or any two spades. I would probaly raise more on the flop, and check-call a turn and wait for the river to make up my final mind. If it's a spade, im probaly folding to anything larger than ½ pot. Otherwise i would call, it really looks like he just flopped two pair or maybe just top pair.
