More light fluff but light fluff I *really* liked. The idea of aliens disguising themselves as little old ladies because all little old ladies look the same is great, some fun technobabble on how their knitting is making energy for their ship, and the plot being foiled because the needles touched is the right amount of silly.

The characterisation is also on point here, Martha gets to save the day on her own, and 10 mostly ignores her, so yep, got their season 3 dynamic down perfectly.

I also like the ending with 10 cooing at a baby, and that last line about all babies looking the same is a fun note to end on with just the right hint of creepy for the kids at home reading it.
