I think Monica, Kimmi and Kelly was probably on good terms in the beginning and was probably going to team up and go against Spencer.
Then I think Kimmi must have seen Monica getting closer to Spencer and she's probably think that Monica is telling Spencer everything. ( But Jeremy is right there, so maybe this isn't when Kimmi grows suspicious of Monica. )
Which I think leads to Kimmi talking to Stephen about Monica being a snake in the grass.
I think Kimmi will get Stephen, Kelly, Jeremy and Spencer to blindside Monica.
