Question about season 2 episode 2

Minor spoilers ahead.

So I'm rewatching the show with my friends and we got round to this episode. In the chapter "william confides in Dolores" which starts around the 53 minute mark, it is a young William talking to Dolores and he says the phrase "you know who loves staring at their own reflection? Everybody". When he says "everybody" I am sure they overlayed Ed Harris' voice just for that word. Maybe to signify William is ageing and developing towards the mib? Idk maybe it's nothing.

I asked my friends and they weren't sure but it stands out to me and I can't unhear it. I can't find any discussion on something which is kind of minor but I was wondering if anybody else noticed it
