The human was immensely distrustful of ponies, but whatever secrets he could hopefully supply might just give the crystal empire an edge, something to help give Cadence that much more independence from Canterlot. Or else she'd find a way to eliminate him if he was too much of a threat.

She had to be certain before she tried anything. Whether she wanted it or not, Masquerade was participating in this mission for her sovereign's best interests.
