The idea of inventing magic with Caleb absolutely thrilled Essek, it was because Essek had felt the same way-- when they had created that spell together to bring Veth back to her previous form, a combination of dunamancy and transfiguration; it had exhilrated him and he leans forward as well, so that the two of them are now in essence leaning in close to each other. This managed to set off a chain reaction, especially when he heard Caleb's admittance as to when it had started on his end.

"I..."

A flush colours Essek's cheek that only amounts to a plum a shade darker than his lavender skin, though even though he flushes-- he still finds himself a bit bolder, because now he knows what he wants, and that is for Caleb to understand his own level of attraction. "You know, I think the moment I felt myself pulled toward you was when you told me you were 'always prepared' and showed me your spellbooks." a wry smile, "And even more so when we were working magic lessons together. Though I know that now? We will approach the table as equals and that is rather exciting."
