* SmugSnake:
* TheLancer: To Michael [[spoiler: until Amy framed her for poisoning half the cult members.]]

* [[spoiler: TheMole: For Ilaria.]]

* [[spoiler: FaceHeelTurn]]: If the first season finale is any indication.
* GlowingEyes[=/=]TechnicolorEyes: After Hatake somehow cures her from infection, her eyes become the same luminescent silver color as his, implying that this unnatural eye color is a side effect of the cure. Hatake provides her with contacts of her original eye color with which to mask them in the following episode after Julia discovers that her new eyes have an extreme sensitivity to bright lights.

* [[spoiler:HeKnowsTooMuch: Almost to the point of being invoked. Balleseros uses her to get the information he needs, then kills her so she can't tell anyone else.]]

* [[spoiler:KarmicDeath: Daniel stabs him in the chest with an ice pick. The wound itself is not instantly fatal, so he proceeds to remove the Major's protective clothing, leaving him to be killed by the elements; similar to how Balleseros himself disabled Doreen and left her to be eaten by the rats.]]

* [[spoiler: CruelAndUnusualDeath]]: Hatake [[spoiler: decapitates her and puts her head in cryogenic storage for reasons as-yet unknown.]]
