I figure Aqualad's either been secretly working for his "father", or that they did something to his mind when he was captured in Cadmus. It was too short a time to clone him, but they could have re-written his mind for all we know, then begin building up evidence against the other teammates as the real mole. With Artemis, Martian, Superboy as suspects, and Red Arrow vicously hunting down the culprit, who would ever suspect that the teams friggin leader is the inside source! Sportsmaster could have mentally activated him when he let slip about the mole to begin with in "Targets"!
