My theory is that she's Agent Carter's child. Just placing it down here for the record.
Might actually make sense - ABC could use an excuse to get Emily Vancamp, who stars in Revenge and will play Agent 13 Sharon Carter in Cap 2 (which Bob noted is around when the season finale happens), jumping between film and tv ala Colbie Smulders, in addition to the crossover potential when/if they get the Peggy Carter solo series off the ground. If anyone should drop that bomb, it should be her "cousin."
The reveal that Skye is connected with Shield is both plausible for why she's been kept around despite being a wild card and really depressing in the "this is your destiny" trope. But her knowing more than the Avengers just deepens my confusion for why a seemingly random anarchist is being given this much knowledge. With the potential for a mega crossover that sees Shield fall apart and the Agents teaming up with the Avengers as the "rebels", I can only hope Stark points all this out in the snarkiest way possible:
Skye: "I know things are crazy right now, but you need to know - Coulson's alive."
Stark
turns to other team-mates) "...who is she? How does she have clearance for this info? Why don't I have clearance? I want clearance."
Also, regarding the Red Skull - WHERE THE HELL IS HE?! There's no way he died in Cap 1 (especially with my theory that no actually got killed by the Tesseract since it may be the Space Infinity Stone and just teleports people): he's one of the most prominent villains in the entire franchise. I know Hugo Weaving's expensive, but it's been way too long without finding out if he's officially gone.
