Teegan

Teegan is a ChemiCo employee and a close friend of Elro's. She is a minor, but important character who has known Elro long enough to be able to discern the motives of his actions and act around them. She is his partner while he works as a ChemiCo Chemist for the One Concern. In actuality she is also secretly a ChemiCo Contra and shares their hopes and goals to help the world rely less on Ivory during the shortage.

Background
At some point in time Teegan and Elro were introduced to each other either prior to or after both joining the ChemiCo Contra. One of the two of them may have also have been the one to introduce the other into the Contra. They remain partners for an undisclosed amount of time, but enough for Teegan to come to know him very well and know how to translate his choices.

Teegan is more than willing to report Elro if it means protecting the Contra and its goals. Elro creates a dual-injection serum that causes Agents to explode, and proposes using this to destroy One Concern from the inside. Panicked, and refuting the idea of murder, Teegan repeats that the Contra are not terrorists, but these words do not alter the future motives of Elro.

Prior to the game, she and the rest of the ChemiCo Contra within the building help Elro escape after he lashes out at Grey.

Story
Teegan is first introduced in the One Concern West. She expresses mild surprise to see Robin but fully understands why she is here, to rescue her brother. Elro has told Teegan a lot about his sister, expressing how frail he thinks she is, but Teegan comments to Robin that the rest of the ChemiCo Contra believe that she is quite the opposite.

Teegan then explains why Elro is a wanted man in the first place: he has recreated an activator that ejects Ivory from whatever it is combined with after stealing the information concerning a failed experiment that was claimed to be for rocket fuel. When used, it turns the target into instant Detritus dust. In anger towards the loss of his father and believing their sympathy to be patronizing, he used this on and killed Agent Grey. Teegan then instructs Robin to find the Usurper Gun for her Stun-Gun and leaves to watch the One Concern assembly before she is found out to be a ChemiCo Contra.
