River is Extremely Pissed Off...

Although her pretty face doesn't show it, she's absolutely furious.

Reason: Marigold Racket tried to move onto the island that they were eyeing...trying to slickly do a right of ownership by possession. "Not so fast, bitch..." River may be good, but she's not above a good old-fashiong screwjob. Purchase of property and an eviction notice "This is our island, get the fuck out" to Marigold Racket. Adios bitch, checkmate.
