Following a displaced raptor through an anomaly, Matt ends up in Victorian London. Realising its to blame for several gruesome murders in the area, he tracks it down only to find Emily attempting to do exactly the same thing. Meanwhile, back at the ARC, Abby knows she has to try and reconnect with Connor; they've been spending too much time apart. But a nasty encounter with April on the way to his lab makes her wonder if Matt is right - Connor is up to something in his lab that she isn't meant to know about.
