Make something up

"Well, the-the truth is...." Now what? Telling 'her' that Jehuty's previous missions, as well as this one, were video games might fry ADA's circuits. Which might be fun to see if you weren't so high off the ground right now. So...

"The truth is, i'm an associate of Rock Thunderheart. He's the one who told me about this frame." You silently pray ADA isn't equipped with a lie detector.

[That does not explain why you are inside this cockpit.]

"Well, i'm the runner, of course."

[You are not in my data as a runner.]

"uh, b-bureaucrats. Always losing paperwork. Its just an oversight, please don't worry about it."

[Sensors detect abnormalities in heart-rate, breathing and eye dilation. Conclusion: you are lying.] Oh, crap! [However, since I do not have a designated runner at present, and because allowing an unknown person to be a runner has previously been satisfactory, I will not purge you from Jehuty.]

"Whew! Thanks, ADA. i'll do my best to...do..what it is we end up doing..."

[That is not reassuring.]
