Collectaholics
7pm, BBC2
In a series that mixes up elements of Antiques Roadshow and The Hoarder Next Door, Jasmine Harman and Mark Hill meet people who have caught the collecting bug – badly. Margaret is so obsessed with royalty that her home is rammed with commemorative plates, dolls and more. Can Mark convince her quality trumps quantity? We also meet amateur naturalist Chris, who is worried his specimens might end up as landfill, and Jack and Jan, who have built a home to house their collection of mid-20th-century designs. Continues tomorrow. Jonathan Wright
Ordinary Lies
9pm, BBC1
Hard day at work? How about spending an hour in an ever-tightening ball of cringe? Danny Brocklehurst’s tonally cavalier drama about a car showroom full of implausibly reckless and immoral people continues, with the story of determined womaniser Rick (Shazad Latif). Couch-surfer Rick is given a bed by Mike (Max Beesley) in his big-boss mansion, and meets Mike’s alluring 15-year-old daughter (Holly Earl). The story goes where you hope it won’t, treating a grim subject with nothing like the required severity. Jack Seale
Dara and Ed’s Great Big Adventure
9pm, BBC2
Ó Briain and Byrne’s pan-American peregrination closes with a trip from Costa Rica to Panama. Setting off from a nation designated the happiest on Earth, and having survived the ominously named carriageway Cerro de la Muerte, spirits ought to be chipper for the comic coupling. But then they have to wade through a bog of bureaucracy at a border crossing. Luckily, the wonder of Panama, and the canal bisecting it, promises to lift spirits before the finish line beckons.

Benefits & Bypasses: Billion Pound Patients
9pm, Channel 5
According to this doc – part of C5’s finger-wagging Brazen Britain season – it already costs more than £250m a week to treat illnesses brought on or worsened by obesity. If we cannot lay off the booze, fags and fast food, the NHS will be unable to cope. These case studies of patients being treated for “self-inflected illnesses” – a 30st woman unwilling to diet, a lifetime smoker coping after a leg amputation – are certainly emotive, while footage of gastric bypass surgery will make you pause before ordering that pizza.

Meth and Madness In Mexico: Stacey Dooley Investigates
9pm, BBC3
Impressive work from Stacey Dooley here as she heads to Mexico to visit the frontline of the insanely brutal drug war, finding how the production of methamphetamine has ramped up violence and cartel activity to a terrifying level. She dons a mask and observes a meth cook knocking up a batch in a shack out in the wilds and – in a particularly chilling interview – speaks to a contract killer paid a few thousand dollars a month to do the cartel’s murderous bidding.

Geordie Shore
10pm, MTV
“It’s gunna get messy.” A bold declaration from standout star Charlotte Crosby as the structured-reality sensation returns for a 10th series. The impeccably groomed posse arrive at the hallowed house with a pumping soundtrack and clear intentions. Two unfortunate Shore-ists must dress as carrots and deliver a tash-ogram, while Gary faces an eyebrow restyle. Fancy watching people swear, showcase dubious sexual politics and get “mortal” on tequila? You’ve come to the right place. Hannah Verdier
Teens
11pm, Channel 4
Episode three of the series charting the woes of a group of sixth-formers focuses on romances that, were they narrated entirely through the medium of their beloved emojis, would merit a sobbing face or 10. James and Peter are sweet, cerebral 17-year-olds who have their sights set on schoolfriend Shauna, but neither can express his feelings. Meanwhile, Melissa – who regrets having had sex for the first time with the wrong person – hesitates when a friendship develops into something more. Hannah J Davies
