that rout is the "high power maid" route, which is different from the "low power maid" route. high power maid is triggered by being female when you turn into a maid (tessa only has 5 influence, which she can either spend on your genderswap OR giving you a new mindset. if youa re already female, then she can just brainwash you immediately). the high-power maid is more under Tessa's control, so you will have less control over lewis's actions. you can't claim any maids for yourself, but you should still be able to lure them to Tessa for her to take control of herself.
