 They are going to the test in Jones' van, but Walker has been using it to fulfil a blackmarket order for Warden Hodges, the greengrocer, and has half a ton of onions.These cause the platoon (especially Pike) some discomfort on the journey and Hodges is so incensed about the non-delivery of the onions that he follows them.Before the start of the test, Wilson shares some information from a friend who previously took part in the test, where the test officer will fire a lot of questions at the platoon and then leave the room, whereby someone else comes in disguised and plants a bomb.
