At this point in his day, Edgar doesn't even blink at the news that there are other other Andrews out there (or at least there had been). The absorbing part does get a few startled blinks from him, though. How unexpected.

He has no problem with the idea of needing to carry a larger Andrew back to the TARDIS, if need be. They can't be too terribly far away now, anyway. But he has to be able to tell Andrew so. With a pointed glance toward Daine (just in case she needed to provide encouragement and/or reassurance), Edgar holds out his free hand to Andrew.
