Returning to Dr. Garrow
Regardless of what decision you make, you have to return to Dr. Garrow in the Interchange after running the ERA Command on the Data Interface Console. Of course, how you are greeted by Garrow depends entirely on what choice you made.
If you simply ran the ERA Command, Dr. Garrow is pleasantly surprised. Of course, she basically tricked you into erasing key details about Oberon and the Windscale Plant that could have been helpful to scientists in the future. After some initial dialogue, you can ask the doctor some questions about Oberon, the Quarantine Zone, and your eventual escape.
On the flip side, if you decide to read the files against the wishes of Dr. Garrow, she will not be pleased when you come back to the Interchange. However, you’ll still be able to continue on with the Dr. Garrow investigation in Atomfall and ask her questions about Oberon and your escape.
In either case, Dr. Garrow asks you for one more thing before you can escape the Quarantine Zone: a sample of Oberon. This is the final mission in the Dr. Garrow investigation and one of your final tasks in Atomfall if you choose to follow this main story lead. Think carefully about whose side you want to take in Atomfall, as whatever side you take will lead to a different ending.
