The reason Melina and John Morrison were together at the WWE Hall Of Fame ceremony this year was because the two are once again dating.
According to one WWE source, the reason Melina was crying when she was drafted to SmackDown! (backstage at RAW, not on television) was because she was worried about being split up with Morrison on the road.
As it turns out, WWE moved Morrison to SmackDown! in the supplemental draft to avoid issues there – among other storyline-driven reasons.
