This is a classic - a neuro with the ability to roll back time - but also records the previous events and then alters them to try to stop the team from intervening. The special effects are spot on, plus the Riley / Hot Girl (anyone know who she is ?) sub-plot was very clever.
In the first loop Jane dies and Connor stops him, the second loop Jane stops him, the third loop Jane goes back with the neuro and then tries to control the situation.
After the previous filler episode this was a welcome change. Not too sure where the series is heading - especially with the Connor/Jane situation
