“The Depths” is episode eleven of season four of Sanctuary.
Will and Magnus are in the Sanctuary discussing the network’s finances. Will suggests combining some of the smaller Sanctuaries, because he thinks they are haemorrhaging money. Which they are.
Henry enters and says he’s got into the databases thanks to the files that Tesla gave him in “Resistance”. Henry has discovered details on three SCIU teams that are heading out; one to Baton Rouge, one to Bolivia and one to East Finchley station.
The Bolivia one strikes a chord with Magnus. SCIU is heading to the desert in the high Andes. There is an elusive Abnormal that is said to live there, one Magnus’ father gave up looking for, an Abnormal that is a huge feathered serpent. One that gave rewards of strength and wisdom, which the Aztecs named a god after – Quetzalcoatl. Magnus’ father had led an expedition to find it in 1909. It failed and he was the only survivor. Following this, he said the Abnormal should be left alone. So Will and Magnus are heading to Bolivia.
In Bolivia, the SCIU team has already beaten them to the Abnormal, and captured it. Magnus and Will stun all the escorts, but are themselves stunned by the scientist heading the expedition, a cryptozoologist called Michelle Moran. Magnus tells her that SCIU is out of its depth, but Moran doesn’t listen. She has her troops shoot the ceiling to make a route to the surface to take the captured Abnormal out, and Magnus is proved correct. The serpent escapes its bonds and there is a massive rock fall.
Will is badly injured and Magnus not so much. The entire SCIU team looks to have been wiped out. They are also trapped underground and need to find a way out. Then Will starts getting better, rather oddly considering his injuries, and Magnus decides her ribs were bruised, not broken, neither twigging to what’s happening immediately. Then the evidence becomes too obvious to ignore as Will’s wound starts healing. Magnus decides that the water she found must be what was responsible fro the gifts the Aztecs mentioned.
Improved healing is only one change; there are others too. Including side effects. The water seems to be functioning like a drug, and drugs can have bad consequences. During the journey to try and get to the surface, Magnus and Will end up having some pretty vocal discussions.
Meanwhile, back at the Sanctuary, Henry is recording a video for his (as yet unborn) son. He keeps getting distracted and going off on tangents, and decides to film a new piece of kit he is working on. Very buggy kit at that.
