My answer above.
Deny does not exist. Never did.
Tanpi has two sons: Kulso and Rovi.
Tanpi lends money to reuven.
Rovi dies childless, leaving his wife Kilonia.
Tanpi dies.
Reuven is considering returning the money to Kulso.
Reuven should not, lest Kulso be meyabem Kilonia.
If he does, people will think they are married. And then when he is mekadesh Kilonia’s sister Chorga, they will think it is not kiddushin.
Hashta d’asinan l’hachi, we may as well say that Rovi is also horaso shelo b’kdusha. Oh well. So you don’t even need the full cleverness of my answer.)
