It was clear that the beauty in front of him was doubting him, and truthfully he found it bothersome to keep pretending as he said,
"Spying on you, of course!"
"Stop lyi… What!?"
The beauty was ready to catch him lying and then pressure him to admit that he was spying, but Roy's response took her out of the track, as he admitted it directly.
Roy was quite happy with her reaction, as he looked at her face with a teasing expression, and repeated his words,
"Spying on you, of course! You don't expect me to pretend like you are my friends and partners when you have ulterior motives, do you!?"
This came as another hit to the beauty's thought process, but she managed to regain a bit of clarity as she continued asking,
"How much!?"
"Huh!?"
"How much did you hear!? Up to which part!?"
"Your uncle found me, didn't he!? You don't think that I stood around after that, do you!?"
"How much did you hear Roy!?"
