Me too! This is definitely the kind of show that requires discussion :)

The finger tattoos were done off screen, the lady who explained stuff said, "come with me" right before she put her inside the giant chocolate orange? (that's what I think of when I see the time travel device)

And so now also we have established antique travel devices, modern ones, and tech that cuts across alternating realities. Is it possible that Kiera could travel ahead into the new timeline, to check her progress? Idk, but I agree, this ep is going to need a rewatch!
