In no particular order:
"You really are intriguing. I bet you'd make for a worthwhile debate partner on the subject."
"You really are an intriguing one."
"In any case, you truly are interesting. You never cease to intrigue me."
"I see. So we even share that perspective, do we…? You truly are fascinating."
"*chuckle* You truly are intriguing."
"I'm sorry if I'm prying. You truly are interesting."
"You truly fascinate me. I'll happily accept your gift."
"Haha, you truly are well-composed."
"Hahaha, you truly are intriguing."
"Leading your team this far in search of an infiltration route… You are truly amazing…"
"50,000 coins, hm? …You truly are special, Joker."
"You really are― No, never mind."
"You truly are interesting… Quiet, yet possessing the courage and determination to take action."
"Heh… After all this, that's what you have to say? Seriously, you really are…"
"You really are a strange one. You do realize talking to me is a waste of valuable time, right?"
