The River Runs Red [Murder]

Plot Name: The River Runs Red
Clans involved: RiverClan
Characters Directly Involved:  Elmstorm (Karuna), Louse (Midnee), Sprucebark (Speedy), Poppystar (Xaan), Cindersky (Moon)

Will there be code-breaking?: Technically no, as Louse is a cat outside of the Clan and therefore not bound by the code.

Explain your Plot: Louse is not a fan of RiverClan, and Elmstorm is known to be aggressive towards outsiders on his territory. He also never seems to know when to back down from a fight. Even if he is losing, he will keep going until the bitter end. So what happens when there is no cat around to save him?

How will this impact the characters/clans involved?: Sprucebark will lose his only son, Poppystar will lose her grandkit and warrior, RiverClan will be down a cat at the paws of another warrior, and Louse will get some vindication in killing another RiverClan cat

Why should this plot be approved?: I was already planning on offing Elmstorm, so this plot will create a fun and believable way of doing it, as well as giving Louse one more kill toward beating Tara's record.
