She'll be selling it to Daybreak under the banner of WITCHES ARE AWESOME AND SHOULD UNLOCK THEIR FULL POTENTIAL. And she'll be arguing that the best way to make London safer for witches is to empower witches to fight back with every tool at their disposal, including fae. The fae shouldn't hold any territory in London, and Samantha's policy is going to pave the way for witches to take back what's theirs.

She'll be making a speech along these lines at the Imbolc event, Lancelot is gonna love it.

As for selling it to Lancelot, she would be very interested to meet Lancelot! She'll want to know where his true allegiances lie. Is he very much Sylvia's man or can she persuade him that this is for the greater good of Daybreak? If she has to, she'll ignore Lancelot and go straight past him but she'd like to get him on side if possible.
