This show really had a thing for foreshadowing seriously.
I’m not surprised that they gave us a shot of Skye surrounded by all that alien writing and what not, and esp the look she has on, it gives me the creeps too.
And yea, i do think there would be a time where her dad would try convince Skye to go on the darker side when tensions are high between her and Coulson esp if Skye finds out certain things about SHIELD (like how technically they took her away from her parents which resulted in her parents looking for her and killing that village). Skye is someone who gives a person such loyalty and trust, like the way she was following Coulson’s orders in that short sneak peak just proves it. She has trust in Coulson so she is loyal to him; but I also feel like Skye is someone who can pull that trust right out from under you the second she feels like she has been played or feels as though they’re lying to her etc. So that would be interesting to see.
And I think Coulson knows about her and Ward, I don’t know if Skye ever actually shared everything completely; like how there were actual feelings involved before she found out he was Hydra etc. but im sure Coulson knows enough to know she had fallen for him and vice versa considering he says that she is only one who can talk to him.
