Collar Stained With Blood - Episode 6

A man is confronted by another who accuses him of being poisoned. The man denies it, leading to a violent interrogation where his captor demands to know who sent him. The captive reveals he works for the Revolutionary Army and that a mysterious General wants the interrogator dead. After obtaining the location of a target named Marcus, the interrogator lets the captive go, sending a message back to the General: he will hunt down their people, starting with Marcus. He then remarks with curiosity that his captive used a trick he never taught him, hinting at a past connection.
