Season 1 of Archer is back on Netflix

With the squareness gun, it’s a bit a like the sonic screwdriver. You’ve got to think about where did Captain Jack’s squareness gun end up? Well, it ended up in the TARDIS, didn’t it? ‘Cause Captain Jack left the TARDIS without packing in Parting of the Ways; all his gear would be there. In fact, in my head and so far as that matters, in the world of my head, it’s not only a sonic squareness gun, it’s the same one as Captain Jacks old one pilfered from the TARDIS locker by River Song.
