Shatabdi is elder than sumer...sumer and rudra are probably of same age...they were in the same class in school...so she's elder to rudra too...hence devarji and not jethji.
Technically Maithali is also supposed to call Rudra Jeethjisa...not just Shatabdi. Its weird... Paro once said she was the eldest daughter in law... thus Rudra is the eldest son... Or else Paro was referring to herself being the elder son's daughter in law (between Dilsher and Danveer) ... which makes her the eldest daughter in law. Also Koyal calls Rudra Kakusa when he is her taujisa... if Rudra is in fact the oldest. Edited by sarita_barun - 9 years ago
Sumer and Rudra are more or less the age so Shatabdi can call him devar just how Koel calls him kaka. Paro meant that she is the bahu of the oldest son, Dilsher and not wife of the oldest son which is technically Samrat.
