Pyotr Stepanovich suddenly remembered that not too long ago he had had to pick his way through the mud in the same fashion in order to keep up with Stavrogin, who was striding down the middle, as he was now, taking up the entire pavement. He remembered this whole scene, and was gasping with rage.
Pyotr realised how pathetic he made himself for Stavrogin. I'm sure he seethed at 'You are a beauty… I love beauty… Without you I am nothing… You are the sun and I am your worm,' too. Not because he denounes himself; Stavrogin is stil his 'sun,' but because he's so lost now that the 'sun' is not here.
