Season 3 Episode 7
The team have a lot to deal with when an anomaly disgorges not only a dinosaur, but a medieval knight in hot pursuit of the "dragon" he is sworn to slay.
- All Myths Are True: Naturally, the Dracorex (and possibly other Cretaceous era dinosaurs) are flat-out confirmed to be the source of the legends of dragons in medieval England.
- Artistic License – Paleontology: Dracorex probably didn't look as draconic in real life as it's depicted in this episode.
- The Atoner: Sir William Mornay, the knight in the episode, is a former mercenary seeking atonement for all the men he killed in the Crusades.
- A Day in the Limelight: For Sarah, certainly.
- Bad Present: William believes he’s in hell for most of the episode.
- Bar Brawl: Sir William gets into one of these with Connor, Danny and members of a biker gang (All of whom get thoroughly trashed by the knight).
- Butterfly of Doom: Invoked by Sarah when she stops Becker from shooting William to defend Abby, warning that killing him could change the future for the worse.Sarah: No! If you kill him, history could change for the worse! His children will never be born...and who knows where it will end.
- Casual Time Travel: Sarah indulges in a bit of this, going through the anomaly into medieval England to get some information on Sir William.
- The Determinator: Sir William is determined to slay his dragon no matter what. He has justified reasons (as he believes killing the dragon is the only way he can atone for his sins).
- Didn't Think This Through: Connor and Danny try to subdue William by punching him and hitting him over the head. Given he's clad in full plate armour, needless to say he shrugs off their attacks.Danny: (after two failed attempts to punch William) That's just made you cross, hasn't it? (A grinning William nods then punches Danny in the face)
- Dinosaurs Are Dragons: The Dracorex has a very dragon-like design (including fins on its back that resemble wings) and is implied to be the origin of European dragon myths.
- Earn Your Happy Ending: After all the crap he went through in the present day, Sir William is returned to his proper time by the team, where he's met with a hero's welcome by the local villagers for driving off the dragon terrorising them and is eligible to court the noblewoman who'll become his wife.
- Evil Redhead: Subverted: Although Sir William is determined to kill the Dracorex, he's not evil, just a Fish out of Temporal Water.
- Fish out of Temporal Water: Speaking of, the Dracorex is a rare example of a creature that is this trope two times over. It first came through an anomaly from Cretaceous North America to 15th-Century England, then through another anomaly into modern day England.
- Herbivores Are Friendly: Averted: the Dracorex is injured and confused, making it lash out at anything that gets too close.
- Heroic BSoD: Sir William goes through one of these when he finds the ruins of the church he set out from in the present day and his tomb within its walls, convinced he's dead and trapped in Hell.
- Hidden Depths: Who'd have thought Danny knew Latin?
- The Lady's Favour: A noblewoman gives Sir William one of these before he sets out on his quest against the dragon. Sarah's research leads her to discover the woman will become William's wife if history follows its correct course, hence why she's determined to return him safely to his own time.
- Not Worth Killing: Sir William decides Connor is this during the Bar Brawl.Sir William De Mornay: You are too feeble an opponent to be worth killing.
- Tempting Fate: Connor asks how hard can it be to find a medieval knight in Central London...only to turn a corner and find a festival going on with plenty of people in medieval costumes.
- Walking Armory: William carries a longsword, a morningstar, a battleaxe and a lance to slay the “dragon”.
- Would Hit a Girl: Subverted: Sarah knows William won't harm her when he demands the Dracorex's location, since it goes against chivalric rules. She's right...but he's not above kidnapping her and forcing her to take him to the dinosaur's location at the tip of a sword. Played straight when he tries to fight Abby when she's protecting the Dracorex.
- You and What Army?: At the episode's end, Connor goes round to the guy who won Rex from Abby's brother in a poker game and tells him to hand the lizard over. The guy in questions invokes this trope, at which point Connor points out Becker and the gun toting soldiers behind him. The guy wisely hands Rex over.
