“Torch” is British for “flashlight”.

Seras: How many ideas do you have?

Pip: Oh, loads! Pepper spray, only with garlic instead of the pepper. Torch-sized pocket sunlamps. Christian pop music tapes…

Seras: Hang on a bit.

What were you planning to test these on?

Pip: Er…well….if I tell, will you promise not to hit me?
