The episode ended on a cliffhanger when Lana was called to diffuse a nail bomb left hanging from a door handle, with a hostage chained to the other side.
Viewers think they've worked out who is behind the terror attacks already and are pinning the blame on Lana's boyfriend, DI Youngblood. Fans of the show became suspicious after Youngblood dismissed Lana's hypothesis that the bombers are setting up the attacks to make it look like an Islamist terror group is behind it.

Other viewers were disappointed that Adrian Lester's character didn't return in the second episode, after being killed in an explosion at the end of the first. One person tweeted: "Really enjoying #TriggerPoint so far but I'm disappointed we lost one particular character so early (I won't say who) as we don't see them on TV enough these days, great actor," while another added: "Can’t believe #TriggerPoint blew up Adrian Lester in episode one."
A third person agreed, commenting: "Gutted Adrian's character has been killed off! Won't be the same now."
