About the person waking up to Tigress and Kaldur, I think that was actually Nightwing, considering that he was fighting against Tigress. As for the person waking up to Bart, I'm thinking that that was actually Blue Beetle, considering Bart's worried face and the person's looking through scanners and some sort of goggles while waking up.
