AKs make this call??

[rockythecat99]

No real reads I just got to this table a couple of hands ago. Besides my flat call which I think I shouldve reraised to give me a better idea where I was at. Who makes this call and who folds and why?? Take into account that I could care less about anything but making the final table.
