I loved Jef's love letter to Emily.
One thing I noticed is that JEF is the only guy who talks about Rikki over and over - not just "Yeah, we'll all be one happy family together," which some of the other guys do too. But he really visualizes things he'd DO with Rikki and mentions those things specifically. He really does include her into his thoughts about what a life with Emily AND RIKKI will be like.
