for the maid, you need the hypno-pill from the sexshop
the second one I don't understand, why send agent after mel? What is the quest?
Thx for the thing with the Pill, and for the Melissa part, on the Chart with all Quests Melissas are red, ill put a Screenshot here aswell so u can maybe see what i mean.
You either should be able to give the agent the mission to retrieve the data, or you already did and it is in your locker in school
