[The ninja seems assured enough, and moves like an accomplished warrior; though already Kratos is picking out weaknesses and matching them up against Lloyd and Colette. His conclusion is not in Sheena's favour, if it came to an out-and-out battle; he's trained Lloyd almost since he could properly walk, and sometimes Colette as well. They complement each other.

[A hidden attempt wouldn't be easy, either. The Sages were both half-elves, with mana-senses; at least Raine would notice someone following. This assessment is hidden behind an impassive face, and Kratos meets Sheena's gaze squarely until she looks away. He answers Yuan first, however.]

Raine knows how important this is. She won't let them linger for long, especially since she'll consider it more strategic for you to have taken me out of the desert.

[Finally Kratos steps away from the bookcase, taking a stance a few feet away from Yuan and Botta, flanking Sheena.]

Because Colette, when she finds out that the worlds are vying for one another's mana, will be determined to save them both. Killing her will perpetuate a system. Her becoming an angel won't necessarily do the same, but it may grant her the power to help solve the problem.
