The Adalind back in S2 isn't really the Adalind at the end of S4/beginning of S5, who was making choice that would keep her son alive. Old Adalind took pleasure in messing with Nick's head like that scene at the jail cell. The Adalind around the time of Kelly's birth was tip toeing around Nick, not being manipulative like the old version. She couldn't afford to play games with him when she was still so dependent on him. She honestly didn't expect him to the her and Kelly in at the beginning of S5. The only time she wanted to ensnare a man to be a father (Viktor) was after she found out she was pregnant, so as to hide that Nick was Kelly's father. With Nick, everything she did was above board. As much as she wanted to be with Nick as the episodes progressed, she also wanted her independence, this was before their kiss and eventual bedding. If staying with Nick was the only thing she concerned herself with she wouldn't have left him for Diana at the end of S5. I know it's not easy to think she could be genuine but S5 and S6 Adalind is practically a different person to S1-S4 Adalind.
Adalind becoming soft and very motherly is about as much "magic" (appealing to a man) as she wielded during S5 but it was never with the intention to snare Nick.
