One last thing RockFace, we all write in past tense, so try to adjust to that. SO instead of this:

"Julian walks to the back of the room. He is greeted by a friend, who begins to discuss the things the two had done when younger."

Write this:

"Julian walked to the back of the room. There, he was greeted by a friend who began to discuss the things the two had done when they were younger."
