One significant thing is that Tomoko jumps from not calling Yuri by name to naming her (relatively) intimately as Yuri-chan. Yuri has consistently called Tomoko "Kuroki-san" and the development here means that, in addition to calling her by name, Tomoko has actually deepened the intimacy beyond where Yuri felt comfortable expressing it one-sidedly. This is huge, for Yuri. We'll have to wait and see how she handles it.
Edit: Ch. 144 resolves this.
