Maybe I'm reading too much into it but I feel like Nigar learned from Hurrem
I'm on a rewatch, and I'm at the start of their erm...relationship?? And I lowkey feel like Nigar got the "love bomb them and make them believe you're gonna die without them and they'll do like...anything." from Hurrem. Its like she watched how Hurrem gave her heart and soul to the Sultan and got him to love and favor her and she's doing the same with Ibrahim, even though on his end it seemed like she was just convenient. She kinda made it inconvenient for him to not be with her with the whole balcony scene and then at that point Ibrahim (the narcissistic lil bitch) looooved how much Nigar was hooked/dependant on him. Maybe like how much Suleiman loved how much Hurrem loved him 👀
