Seto allowed Loki to touch the locket, looking curiously at the man's expression. Hm...?

And then the image manifested in the water, and he smiled down at the familiar face.

"Mokie..." He squeezed the locket gently, closing his eyes as he cycled through memories. This was who he fought for, this was who was waiting for him.

After a moment he looked back up at Loki. "Interesting spell. Does that have other applications?"
