Reply To: Yavam inheriting father who was a ger

Maybe all the pronouns are confusing people. So I’ll give everyone names. Tanpi is the original ger. Kulso is the kid who is ????? ??? ?????? ?????? ??????. Rovi is the brother who dies without having kids. Tosafos’s explanation is that people might think that Kulso is a full fledged Jew and therefore if Kulso does yibum to Rovi’s wife, people will think it is a valid yibum when in reality it wasn’t. This is problematic if Rovi has a brother, Deny, who is a son of Kulso that was ????? ?????? ?????? in which case there is still a chiyuv of yibum on Deny. My question is that if Deny exists then the borrower would have to pay back the loan to Deny. (My question is not about the yibum part.)
