A Friend in Wolf's Clothing

Act 1
After the events of the last episode, Serena is still having trouble convincing Molly to avoid "Maxfield Stanton". Meanwhile, Nephlite himself is wondering why his Star Crystal reacted to Molly's energy. However, he did remember Sailor Moon's recognition of her, planning to extract the scout's identity out of Molly herself. Little does he know that Zoycite plans to watch his every move. As Nephlite wakes Molly up, he reveals who he is and lies about teaming up with the Sailor Scouts to stop the Negaverse to gain Molly's trust enough to help him. In the meantime, Zoycite overhears the whole thing and thinks he's telling the truth, sending the Plant Sisters to abduct Molly as bait for her "treacherous" co-worker. Back with Molly, she calls Serena with Nephlite eavesdropping. As he watches her transform, a fight with Tuxedo Mask for Sailor Moon's life is cut short with Molly being taken prisoner as Zoycite planned it. As Luna notices this, Nephlite reads Zoycite's ransom note involving the Star Crystal, burns it and goes to find Molly.

Act 2
As the Plant Sisters guard Molly, Nephlite arrives and saves her, refusing to give up his Star Crystal. As he gets Molly to safety, she notices a cut one of the monsters gave him and patches him up with a part of her pajamas as a bandage. Molly then asks him out to a chocolate parfait date which he happily accepts, turning genuinely good in the process. Before they could arrange a date and time though, the Plant Sisters strike back with one of them implanting a thorn into Nephlite! While he surrenders his Star Crystal and urges Molly to run, she remains where she is in an attempt to remove the thorn. As it's about to come out though, the Plant Sisters attack Molly with Nephlite shielding her. Zoycite then steals the Star Crystal and orders Molly to be killed as well.

Act 3
Before the Plant Sisters can hurt Molly though, the Sailor Scouts ambush them! Sailor Mercury stops the bombs with Mercury Bubbles Blast while Sailors Moon and Mars combine Moon Tiara Magic and Mars Fire Ignite to finish them off. Unfortunately, while Molly is safe, it's too late for Nephlite who dies in Molly's arms, much to her despair.
