David's motivation

[Deleted]

David's arrangement with Toby made him look like a great detective (not that he was a bad one IMO).

Why did he jump on that occasion? Was his main goal to simply pump up his ego and enjoy his fame or did he want to impress Maddie, and if so - in order to get her to give him the raise he'd demanded or simply make her think higher of him?

It was to impress Maddie and prove to her he was a good detective. I think at this point it was to change her opinion of him and not about the money anymore. By this time, even if he would never admit it to himself, David was deeply in love with Maddie and her opinion of him was very important. David wanted Maddie to think highly of him. He did it for her.
