It's a crossover viewers are now waiting for following the latest instalment of Trigger Point.
The ITV drama returned for episode three on Sunday night and once again had those tuning in on the edge of their seats.
The episode started where last week's left off, with Lana up against the clock to defuse a device hanging on a door in a Mosque with a man gagged and tied behind it.
And if you haven't seen it yet, look away now as there are spoilers ahead.

As the clock ticked down, Lana had to make the decision to make her own escape and within seconds of making it outside, the bomb went off.
A far-right group claimed responsibility for the mosque attack in a cryptic message sent to the police, declaring it was in revenge for the earlier Westhaven bombing.
Later, the team were called to another suspected attack but this time they were also being watched by a member of the group with a sniper.
The episode saw one of the members shot dead and one of the bomb squad's own team killed with the culprit escaping unseen.
However, by the end of the episode, Lana's suspicions lead her to checking on her own colleagues after discovering the group must have military training and experience in explosives.
Trigger Point viewers saw Lana checking the lockers of her fellow Bomb Disposal Squad members, only to find an A-Z of London books of maps with post-it notes and markings to suggest plans for the attacks that had already taken place - and potentially more to come.
And with an 'inside job' now believed to be uncovered, fans have a very clear plea and it has links to Lana actress Vicky McClure's other high-octane role as Kate Fleming in Line of Duty.
@beansontoastpls tweeted: "That look when you realise it’s an inside job and you’ve got to call DS Arnott #TriggerPoint."
"The only way I can carry on watching #triggerpoint is if Lana is really Kate undercover and calls in Arnott and Hastings to find the inside man! #lineofduty #crossover," @LindseyBowden76 said.
@kadi70928314 echoed: "#TriggerPoint we just need hastings arnott and fleming to interrogate! Love a crossover."
"Hmmm... There's a bent copper. Think they need to call AC-12 #TriggerPoint #LineofDuty," @SarahVerity commented.
@Silky65558270 added: "Of course Lana’s going to get the inside man. AC12 experience helps on all fields! #TriggerPoint #LineofDuty #VickyMclure."
And that may be helped by the fact the six-part thriller is from Jed Mercurio, the brains behind Line of Duty and BBC's other big hit, Bodyguard.
