It has become a habit.
If he went on a trip without Helena, he always felt it was boring. Even if he was with his good friends. That's how much he got used to having Helena by his side.
He immediately wanted to go to Helena.
He took a step but stopped himself.
He recalled Helena's words. During this trip, they would pretend to be strangers.
Why?
No reason.
It was just that Helena felt it would be fun that way.
Vernon immediately went along with her plan.
Two good friends pretending to be strangers when they meet each other, when they were actually on their own honeymoon? No matter how one looked at it, it was different. It would give them a different experience.
What would they gain from doing that?
A new experience and also a new relationship, probably?
No matter where this new experience would take them, they only hoped it would be good compared to pretending to be a newlywed couple enjoying their honeymoon when they had already talked about their divorce.
