He gifts her with special gloves that will allow her to pick up objects from afar, dubbed “the Russells”, as well as a pistol. Russell manages to rescue Alyx by destroying the transport taking her to be interrogated and they meet up at his lab where he reveals Eli will most likely be taken on a train to Nova Prospekt and that she will need to intercept the train by going through the Quarantine Zone.

While checking in with fellow Resistance member Olga, Civil Protection suddenly goes on alert. Just as the call finishes, Russell and Eli discover something. She reports normal CP activity but adds that she noticed the Combine moving supplies into the Quarantine Zone for unknown reasons. She receives a call from her father Eli and his mechanic friend Russell as they attempt to steal a Combine reactor.
