Avoiding Jakob has had the unfortunate side effect of leaving Add to his own imagination when it comes to his shinki's feelings. Even if Jakob hasn't done anything to suggest he wants to leave, it's hard to believe that when he can sense his unhappiness. Add's paranoia won't allow him to accept the obvious answer. Jakob never really liked Add when they were both shinki, why would that change just because he's Jakob's god now...?

He's already preparing himself for the worst. This may be the last prayer the two of them do together.

Add slows to a stop once they reach their target, frowning at the man sitting on the sidewalk. The prayer he left them was something about losing everything and wanting a sign...

If Jakob wants to take control of the situation, he's welcome to. Add doesn't say anything, but he takes a slight step back to give his shinki some more space. The least he can do is let Jakob do his job properly before they go their separate ways.
