Re: Multiple targets
Either way you have to win everyone over to some degree or you will get cb-d or if some of her friends don't like you you will get shot down because she doesn't want to make herself look bad in front of her friends, be friendly win everyone else over work on the target then with right iois you can isolate and escalate.
Also use kino early and often on everyone it makes it easier then when you need it to escalate with target later because the kino later will be dismissed as natural and not as obvious. Otherwise if you introduce it later and only to her she will have a red flag go up and then it will be hard to recover.
