I think it's sweet he trusts her so much, but I have to admit i was a bit surprised that he would say she's the person he trusts most. Of course she's acted in a trustworthy way but it's not like they've known each other that long or talked about much, so I just wasn't expecting that. However, maybe he feels that more since they've been in battle together and he may also feel a sense of trust with them being married.
