2. The Rising Tide Is Much Bigger Than Previously Thought
In the first episode when we see a glimpse of an organization known as the Rising Tide, it turns out it was just Skye pretending to be more important (and smarter) than what she actually is. However in the second episode we see her secretly confirming to an unknown person that she's "in" with some form of project. But not only that, she also managed to get the attention of Ian Quinn because of her work for the Rising Tide. If they were an important threat for Shield without having as much equipment as they have, imagine the damage they can cause to the organization if they have someone inside. My guess is that we're going to see what plans they have for the organization during the season finale, and it will probably involve Skye betraying them.
