I suspect that was always somewhat the case, due to a combination of the fact that Lien was the only person who could really hold her own against a full-crazy Lilith, and that Lien seems to have a, shall we say, different way of dealing with people?
That, and there was the whole thing with Lilith kissing Lien after she was fixed.
So what you’re saying is that Lien needs Lilith to wear those cat ear mods
So I’m going to guess that Lien is the only one who treats her normally then?
