Essek watches curiously, squinting against the late sun and light of the portal that Lea accidentally summoned. The weapon was so strange and the portal it seemed to have created made his pained, tired mind want to be interested, but the focus, the concentration wasn't there.

All that was in his fractured mind was the a sudden and intense spike of anxiety when Lea steps into the unintentional and clearly unknown portal and vanished from view. Part of him expected Lea to not come back, to just be gone and Essek would be alone again, left to try and find a way across a flickering bridge and no magic to do so. Once again absolutely alone.

The longer he waits for the other to return, the more his breathing picks up and his eyes grow wide with growing fear.

And when Lea does comes back, the relief makes him feel so light headed that he has to actually reach out to the other person to keep from crumpling to the ground as his knees give out on him. "You-" he has to gasp for air as he talks, "you're back, I-I thought... yes, I-"

There's enough mind to know magic has limits, so he nods and holds on to the other for help through the portal, even as the touch stings with knife sharp tingling. He can steady his breathing when he's back across it.
