I keep getting stuck on him.
Do you ever think he flinched whenever someone said 'Wormtail?' I mean, that was his nickname, given to him by his three best friends/practically-brothers. And as well, they were probably the only ones who called him that. And now, that's the only name he's known by among those who know he's alive, aka the Death Eaters, which were who he killed/put in jail two of those aforementioned best friends/practically-brothers for.
Like, ouch.
