Zenyatta catches up to the other Legionnaires. (Speed outside of Transcendence is not his strong point.) If this was part of the adapted plan, the senior Legionnaires would have given some kind of response before the chase had progressed as far as it did. The disguised team wouldn't have been compromised by their own side.

Being an omnic, Zenyatta is all too aware how one can be hacked and forced to do something one does not wish to. He cannot tell with certainty, but he senses discord within them. Something is amiss. But what?

"I am afraid you will have to explain more before I take any action," he says not to the mysterious voice but to the Legionnaires before him. Zenyatta hovers before them, and his orbs spin rapidly around his neck. He's agitated. "What is happening?"

Zenyatta may need more convincing to leave the senior Legionnaires behind and abandon his role of protecting the president by going elsewhere.
