Yeah and William's shirts have different collars than Louis'. The first page looked like Louis
It could be William, since he and Sherlock like to play while referring to each other. William usually calls Sherlock, 'Holmes' and during the bridge scene he called him 'Sherly'. Vice versa, Sherlock usually called William 'William', and in that scene etc etc.
You're right the reversal could be so significant to whatever happens to their relationship in this arc
I mean I agree William always call Sherlock as Holmes/Sherlock before the bridge scene but Sherlock always call William as Liam from the beginning (except few first time they just met eo ig. Or while he's talking to other people)
ITS BACKK and I don't like what the first page is implying anyways I think sherlock was talking to Louis and not William bc Moriarty????? Never heard him call William that
