Melissa walks in on them, but Alan is too high to explain what happened. In the season six finale, while Judith is giving birth to what is possibly Alan's daughter, Alan and Melissa meet up and have sex in a closet, ultimately getting back together.
While Alan is in the hospital, Charlie's ghost appears to him (It is implied that this is due to a hallucinogenic reaction due to the medication Alan was on.) and explains that his spirit now lives on in Hell forced to live eternally in a woman's body (Kathy Bates) as punishment for his womanizing behavior during his lifetime.
He acts as his brother's spirit guide, though he later confessed that he really could not care less about what he does.
Their relationship goes into season seven where Melissa wants to move into the beach house with Alan, Charlie, and Chelsea.
Alan is happy to live with Melissa at first, but eventually Melissa and Chelsea start taking over the house, resulting in Alan and Charlie staying at a hotel. Evelyn tells Chelsea about Melissa's short lived romance resulting in the girls getting into a fight, and Melissa moving out.
