The question is not when did Medic adopted Angela as his daughter
Is not why would he do this kind of mercyful act as this
Or if she even get to know about his father´s past
Or how did he managed to survive til late 20XX

But

WHY THE HELL WOULD HE HAVE AN OLD PHOTO WHEN U CAN USE A DIGITAL CAMERA
SRSLY OLD MAN

Some old habits. I guess Medic is not really into digital cameras at all.
