Isabelle is very in love with Rico...

Rico's love was Claudine.
Let Derek and Isabelle explain who had killed Rico?
Why now...
Barbie was killed.
Isabelle's love is Jerry!
So she will kill any love interest of Jerry!
Now they are throwing it to Ken. So Woman will get killed. Nice try.
Why Ellen was tormented because of Derek.
Another love and fuck toy/boy of Isabelle!
