In juxtaposition, the brilliant white of the upper jaw's crowns of Nathan and Emma' is almost blinding when compared to the far less ostentatious mildly yellow tinge of the tooth population of the lower jaw, suggesting that either vanity or shamefully neglectful dental hygiene causing substantial damage to the flesh-tearing incisors of the upper jaw, has prompted the two housemates to invest either in dentures or, more likely, in a complete upper jaw arch of titanium dental implants with super-white porcelain crowns.
When Nathan opens his mouth - which is tighly stretched over the upper jaw, suggesting that the implant was inexpertly measured and fitted - it is reminiscent of a crocodile opening its jaws to welcome lunch.
The white light emanating from Emma's (no pun intended) upper jaw could easily be mistaken for the white light that entices the gullible to walk through it into a glorious afterlife, as depicted in "Poltergeist" and other films of the genre.
This is no criticism of Emma or Nathan, just an advertisement for superb implant dentistry performed at our surgery in Bitesville, and if offers the suggestion that, if you do opt for implants, make sure that the shade of its crowns matches that of your remaining lower jaw teeth. The alternative is being ridiculed for having a 2-tone mouth.
One may not criticise Nathan for having ill-fitting implants, but the opinions he voiced during his chat with the climate activist exposed him as a self-serving hyporite, an ingnoramus and a buffoon.
