Sure it does. They were keeping secrets vital to team safety on the side until the very end of season one, and again during season two. They werent upfront with miss martian wiping not only the minds of enemies, but even going so far as to try to wipe kons as well. And they held on to that last secret for a while. Who knows who else she could have altered? Lagaan? Gar?
I mentioned this earlier in the thread, but I believe the reason Miss Martian and Super Boy got left out on the secret was because Wally, Aqualad, and Nightwing were the original sidekicks excluding Speedy, so they had a closer bond/friendship since they've known each other even before Young Justice existed (Artemis being included for obvious reasons). If trust was the real reason for who did/didn't know the secret, then Robin and Bat Girl could have been brought in on the plan.
