...I was quite surprised to discover that Supergirl hadn't actually been Supergirl for about fifteen years.
I started reading at the new 52 as it seemed like a good jumping on point. I did go back and start reading some other comics recently and discovered that Supergirl had actually died in Crisis. I don't know much about this and am still reading up but it explains Death of Superman why there was a big grey mass that became Superman. Who was that? D:
Did the real Supergirl really only return in New 52, over 20 years after originally dieing?
I've only read for four years but feel like I am never going to know enough or stop learning things
