Yeah Lisa is for sure, look at the way she has groomed Sree as a weapon, but as schemers karly and Noirin are right up there imo.

For Noirin though it's just a matter of time until the Nasties target her (unless she can now work to fix her relaitionship with Shree and get herself back into that faction this week... she is fully capable of that), and Karly is happy in her role as a Lieutenant for the time being. Lisa is still definitly the house General.
