ok everyone. i just realized there IS or maybe a bug when trying to recruit Holoryx
(Highly Recommended to save another file before going to the cell; in case you make a mistake)
Once you visit at the Cell; where you find Isaac (Captain) and Holoryx. You'll be having a conversation with them about the their problems. After that ends,
DO NOT GO TOWARDS THE NEXT DAY. you have to go back to the cell AGAIN after the first conversation, so you can actually recruit him.
If you went to the next day, you will never be able to recruit him because the second dialogue went literally missing.
Xperiment, hopefully you'll read this and able to fix it so we can recruit Holoryx :(
