She always has a plan????? What this plan was???
That's a bad screenplay joke, Telltale....
It ruins all the plot. :(
I don't even think that anyone at Telltale knows what plan she has on... it's just an bad excuse to create some suprise, but it totally fails....
If this is the help that Ron gave you about Elaine's role (as you said in an early interview)... better leave him home next time.
Another enigma to solve in the Monkey Island universe.... I'm getting bored with these tricks.
Being propositive: change the latest lines of the game and re-release an updated version, with longer and corrected ending sequence.
