From what she gathered, it seems that Lyan had something on Jack, forcing the young man's hand on doing this. And Jack was the one who found Dante and had him approach Felinda.
Jack wasn't a rash person. He was someone who was very meticulous and plans long term. He loves the thrill of setting up a trap and make you fall into it step by step. You wouldn't know how you got caught until you are in there.
That's exactly how he had been doing. Unfortunately for him, she got a whiff of the bad scent, and had been monitoring Dante ever since. That's why she had always been cautious and didn't let him get his way.
In order to ensure that everything was moving perfectly, Jack used an alias, Wayne to approach Felinda and Dante. In fact, it could be said that it was done to approach Felinda, since Dante and Jack already knew each other.
