Theory:Doctor Who television discontinuity and plot holes/Gridlock

You are exploring the Discontinuity Index, a place where any details or rumours about unreleased stories are forbidden.
Please discuss only those whole stories which have already been released, and obey our spoiler policy.

This page is for discussing the ways in which Gridlock doesn't fit well with other DWU narratives. You can also talk about the plot holes that render its own, internal narrative confusing.

Remember, this is a forum, so civil discussion is encouraged. However, please do not sign your posts. Also, keep all posts about the same continuity error under the same bullet point. You can add a new point by typing:

* This is point one.
::This is a counter-argument to point one.
:::This is a counter-argument to the counter-argument above
* This is point two.
::Explanation of point two.
::Further discussion and query of point two.

... and so on. 

• If the Face of Boe truly is Jack Harkness, it does not make sense for him to die, since he is immortal. ::Harkness still ages, just at a much slower rate; assuming no further time travel, he's now over 5 billion years old. He also gave the last of his energy to open the motorway; this last energy could have been the energy that was keeping him alive. Also, on several occasions in both Doctor Who and Torchwood, Jack "died" and did not immediately revive until some time later. We don't know for certain if Boe really died. It is also possible that being over 5 billion years old has taken its toll on Jack, perhaps even destroying his Immortality eventually, the effects of the vortex and his luck could have 'run out' as said by Ianto in Children of Earth.

• It seems rather silly that the automatic quarantine would let people into the motorway (surely letting the virus in), but not let them back out. What's more, wouldn't any of the later entries to the motorway have noticed that nobody ever came out, or even tried to get out through the entrance shafts.

The quarantine was to separate the lower city from the upper city, not the lower city from the motorway. The motorway was probably sealed to prevent the citizens of the lower city from realizing that they were trapped, as they knew they could leave at any time.
