Absolutely, it seems so obvious that Lisa isn´t behind this. Not saying she´s unable to do something underhanded, but she would be smoother about it and look out for her own interests.
I remember when the show started, I felt so sorry for Kim because Kyle was not nice to her, talked down to her in a very mean way, considering that Kim was older and had accomplished more in many ways. She always acted like Kim was such a stupid little thing that had to be taken care of. Kim proved later that she had deserved it but... I am now doubting some of it, since Kyle is a pure bitch with no loyalties. I never saw it coming that she would mess up so badly with LVP though.
I truly hope that none of these disgusting creatures (Rinna, Erika, Kyle, Teddy) can come back from this. Dorit isn´t even worthy of being mentioned, she´s so everything bad and stupid, so only her supporters really deserve to suffer. For me they are the real monsters (even though she is obviously a monster for the way she has lied and what she did to little Lucy).
