Just popped up

this has just popped up in my daughter's neglected pot of cinnamon basil which she has had on her windowsill from last year. The small seedlings are definitely cinnamon basil, but the tall one clearly isn't.
One of the cress family like shepherd's purse or pepperwort.
A weed then! Thanks h-c
Would definitely go with Pepperwort because of the incredile height and rounded seedpods.
