Why?
Well I chose this title for a number of reasons. First off, I wanted something that related to the two of them. So I decided to focus on their abilities and on the codenames that they have never used. Fuse for Brennan and Synergy for Jesse. But I didn't want to use those specifically as they didn't combine very well, so I looked at synonyms for those words as well as words that were synonymous with their abilities.
Synergetic - I chose this because it seemed to be a good expansion of the word synergy, something along the lines of energy to energetic. My only problem was that I couldn't find it or synergy in a regular dictionary, though I did find synergism (the joint action of agents, as drugs, that when taken together increase each other's effectiveness). I did find synergy in my Medical Dictionary though (correlated action or cooperation by two or more structures or drugs). These definitions do make me think of Jesse's abilities.
Dynamo - The dictionary defines dynamo as 1. an electric generator, especially for direct current 2. an energetic, forceful person. Both of these seem to suit Brennan to a tee. He is an electric generator and he is an energetic, forceful person.
Why Brennan and Jesse?
Why not? ;^)
There are a number of reasons why I would like to see Jesse and Brennan together as a couple. The main reason is that they are two gorgeous guys who would look good together. While my first love is Shalimar & Brennan, there is just something about Brennan and Jesse which caught my eye. They are one of the few slash couples I like.
