Theory:Torchwood television discontinuity and plot holes/Children of Earth: Day Three


 * When Lois Habiba wears the contact lens, she puts them both in the same eye (her left eye).
 * It is possible that it was the same lens, it may have fallen out of her eye. And it's unclear which shots are of the bathroom mirror.


 * The green goo sprayed on the front of the tank disappears and reappears in different shapes several times between shots.
 * Actually, it runs to the bottom of the tank, look at the lower part of the glass.


 * When Gwen is demonstrating the lenses to Lois, several times she looks in different directions and moves her head, but the display on the laptop doesn't move.
 * It looks to line up quite well actually. It is possible there is some "lag" between the lenses and the computer display.


 * It seems a bit suspicious that Ianto managed to buy another coat for Jack that was exactly the same in every way to his previous one.
 * Ianto said that he got it in "army surplus special". Also, it's never been stated that the coat destroyed in the Hub was Jack's only coat. Given his tendency to get shot, burned, etc. he presumably has replaced the coat on occasion. There may well be a surplus shop with a dozen of them on the rack and Ianto knew just where to go.


 * Gwen gives Lois the contact lenses immediately after removing them from her own eyes and expects her to wear them immediately (she doesn't).
 * If Torchwood can develop contact lenses with the abilities shown, perhaps they found a way to make them sterile. That, or the lens case contains a cleaning solution we do not see as many do in real life.


 * Lois doesn't wear glasses, nor is she seen removing any contacts before rather easily putting the Torchwood ones in. Anyone who has ever had contacts for the first time knows it is very difficult and for some people, impossible to put them in without assistance the first time.
 * Maybe Lois used to wear contacts and had a laser vision correction procedure? It is also possible she removed a pair of her own lenses first, off-screen, though the editing suggests this not to be the case. She could just as likely have not worn her lenses that day.


 * The contact lenses that Lois wears use lip reading software. When Martha wore the contact lenses, Torchwood was able to hear everything that Martha heard.
 * Maybe Gwen and Rhys borrowed an early prototype that didn't pick up sound yet At the time that Martha wore them, they had access to all of Torchwood's technology. This undoubtedly includes other surveillance equipment for them to have used in conjunction with the lenses or they may have been made by Torchwood replicating the originals as they were destroyed or damaged in Reset so Torchwood made their own, but couldn't make them pick up sound.


 * Frobisher welcomes the 456 ambassador on behalf of "The United Kingdom and Northern Ireland", instead of "The United Kingdom of Great Britain and Northern Ireland".
 * He may simply have misspoke under stress.


 * Later, when listing the countries which have agreed to let him speak on their behalf, Frobisher refers to "The Provinces and Territories of Canada". The correct formal name is simply "Canada."
 * As stated before, he may simply be under great stress and misspeaking.
 * Actually, this is wrong. Canada is 11 different sovereign states: the 10 provinces and territories, and the federal state ("Canada"). The Queen is independently the sovereign monarch and head of state of all 11; she has 11 separate viceroys; etc. The Canadian federal government cannot speak for the Provinces and Territories of Canada, but the Crown can and does, in some contexts. And it would have been the Queen, not the PM, who delegated to Frobisher, since she's the head of state.
