In chapter 2 of Great Expectations what object that Pip takes makes him feel guilty and nearly gets him discovered?

He steals several things from home that day--food, a pork pie, brandy, and Joe's file.   It is the pork pie, the brandy, and the file that almost get him caught.  When he stole the brandy, he replaced it with tar water, which makes one of their guests incredibly sick.  So not only did he steal the liquor, he also inadverdently made someone sick from the action.  This startles the entire family; next, Pip's sister goes to get the pork pie.  Gratefully, they are distracted by the soldiers.  The soldiers have discovered the filed handcuffs; Magwitch had used Joe's file to saw them open.  The soldiers realize the file must have come from Joe's forge.  This is awful because then Joe looks guilty, and Pip feels horrible.  He has to decide whether or not to confess his crimes.  Fortunately, Magwitch covers for him, and he gets off the hook.

So, stealing almost caught up to Pip in several ways in the opening chapters of the book, each item causing alarm, harm and intrigue.  I hope that those thoughts helped; good luck!
