I personally believe that whole thing was about separating the MC from Noel. Whatever Nael and Gabe have planned is going to require both Noel and the MC to grow and Noel couldn’t do that with being restricted by the bond. When Noel and the MC were separated and Noel went ferel, she basically detached herself from the bond like how Eda wasn’t restricted by the bond before she and Clara visited Nael.The way i see it is that Gabe dose not whant Noel and The Mc to be separated but becuse Noel Died and was brout back by Nael the bond was gone, and with Gabe changing his mind i think that is him being lazy and/or just whant to spend more time with Nael.
I know this is off topic but have you thought about how perfect and necessary it was for Nael to force Eda back into the bond? If Nael had not “rewarded” Eda by binding her and letting her keep her memories, Eda could have fought off Unis herself and Clara would have never made a deal with Ren. All of it is orchestrated by Nael for some purpose, including Clara and Eda.
Anyway, back on topic, Noel is now no longer associated with the bond because she went ferel. I am guessing that was necessary for whatever Nael has planned and that is why Matt was allowed to rampage killing companions without hesitation right up until the moment that the bond between Noel and the MC was cut. The very second she gets what she wants, her and Gabe step in.
