Oh by that argument does Maa consider him beta? Did she not come and slap him when he stood accused of making a baby with Tannu? Why didn't she stop for a moment and say that it's possible he is trapped? He never told anyone he wanted to make that baby and admitted it may have happened while unconscious! Did that make him a culprit!? No, in my eyes but he was given the punishment to marry Tannu by one and all!!
How come she supported Pragya in MMS? Trust her blood but not him??
She should be thankful he still asked why she didn't tell him her problems and doesn't really want to make a deal out of what he saw. He asked everyone to forget about the matter.
And Maa might have remembered how Purvi felt when she was accused! Or may be not! Lol.
And if Beti is chor who is claiming to have taken his wealth by cheating him, hard for him to believe Maa will never do it. And Beti is not even telling him Maa has an enemy in the house. Yet he is sad about it, and of course will go by his heart and save her from going to jail.
It's different from Abhi's eyes who doesn't know anything that we know. We can't see innocent people accused but he doesn't know any of the backdrop where Maa is Tannu's target.
