Quite unusually for this series, the first two parts of the story had their worldwide debut not in the ongoing American comic series, but in its UK sister series Doctor Who: Tales from the TARDIS, appearing in the first and second issues of its third year, less than a week before their respective American printings. Regardless, the fine print on the issues' contents pages still credit 13DY2 1 and 13DY2 2 as their original printings.
The Thirteenth Doctor is back with her friends – Yaz, Ryan and Graham – in a brand new time-travelling adventure. This time she faces the horrific Weeping Angels – who else can help her out but one of her previous incarnations: the Tenth Doctor himself!

What could go wrong?
