Beneath the waving lake, Sej and Reine were drifting away with the lake, as the lake kept on drowning everything in the antiverse, then too we're being pulled beneath into it's darkness, burying them with the water of the lake.
Reine's hand got away from Sej's hold as he was unconscious, and both of them started drifting in opposite directions, getting lost in the water.
They kept on drowning deeper and deeper into the lake, getting further and further away from the light above, and though unconscious, Sej knew that they won't survive this one, that him, along with Reine and the late king Leviath, would be gone, forever...
And when all hope was lost for them, a hand came by and held Sej's arm, before pulling him above the surface, heading to the light above them, ans while Sej was being rescued, another came and held Reine's arm and pulled him above the water too, rescuing him from drowning even deeper then he already was.
