Erich did not remember much of what had happened during his W-7 certification. What he did remember was consuming an ungodly sum of drugs. After that the murder spree he went on, which would cement his legacy as the Germanic Star-Empire's most promising soldier was a complete and total blur.
When Erich finally came to, he woke up in a medical facility. He was not in a clone's body, but apparently the drugs he had consumed were even beyond Tia's ability to manage. However, he was not alone in this facility. It would appear that Emrys, along with several admirals, and Generals were there to interrogate him.
But that was not needed. After discussing with the Doctor just what had happened to Erich, they were more surprised that the idiot had lived to tell the tale than they were about the results of his slaughter. Emrys stood in front of Erich and scolded the man for his recklessness.
