OK  "I don't think so, Adalind is not stupid enough to betray anyone," Adalind has never shown the ability to do what is smart. If Juiette has shown Nick is more a danger then protection by having him shoot Monroe. Adalind will be quick to find a new protector. And the promise to reunite Adalind with Diana would be the only motivation Adalind would need.

The biggest reason for Adalind to betray everyone is, all other seasons that is what she does. Causes maximum chaos and then leaves. Remeber she is not sincer about wanting Nick to help her with her child. She was out of options. And that was the best lie she could come up with. Like wanting to take Juliette powers. That was to protect Adalind not to help Juliette.
