Ok am just rewatching. Her saying thum bhi IS in reference to Anus expressing his love for Maryam!!!
She has just flashed back to Anus saying that marriage is not the final test of love. It’s that he can die for Maryam, and then he says are you now satisfied about my love for her? She remarks in her head that Mariyam is lucky to have someone that loves her= is ready to die for her.
Then Murtasim walks in and she comes back to reality. She asks him about the dying for love question by starting with, “I was just thinking…” because that’s what Anus has just talked about as the ultimate test of love. She ONLY brings rohail up after Murtasim brings him up.
