Jayfry waited behind the tree and waited . It was going to be awhile before the end of the column passed him , so he started to relax and take the first real look around him . It was raining , so the clouds were gray overhead and the cold made his body tighten , and one could not tell if he was nervous or just trying to stay warm in his scantily clad robes . The truth was , it was both .

What is the reason " It was going to be awhile before the end of the column passed him " ?
The column was a regiment or large assembly of soldiers marching in formation .
