If you go this route, V.I.C.I. will not give you cybernetic enhancements as a perk.
(Which means you can sell all of those expensive pieces that you've probably held onto until this point. Make sure to increase your barter to 9 or 10 before selling for maximum profit.)
Below is a guide, plus a few things to be aware of when completing this achievement:
-After getting the module from the commune, you need to go back to Nancy Reliance
-There will be multiple options, you need to pick the one that transfers the AI (Reagan) to Val
**Once you select this, you will no longer be able to deal with the Commune and will not get the bot companion, and will not be able to interact with the Commune, except for V.I.C.I. , the healer bot. Which will tell you that you need to leave, and they don't want to heal you.
*If you did everything right with V.I.C.I. earlier, then you should have gotten the tissue samples and information in order to get the Gipper medic (The Wyman) to heal you for free, so there is no real loss that V.I.C.I. won't help you, because you will have a free medic an entire load screen before V.I.C.I. would be available. (considering you stop here for healing again once in the overworld.)
