::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]].

:::Furthermore, there's no guarantee that Jack was even telling the truth about his nickname. He could have learned by other means that the Doctor and friends were acquainted with the Face of Boe, and be playing an elaborate joke on them.

*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.
