Sena looked back at the location he assume the eyes was coming from, when the leader called, he shift his focus on the already finished stage, "looks good." he then mutters the word, "surprisingly..." Sena was caught off guard, she actually manage to create a stage in an already destroyed aquarium. Maybe she have a knack for construction and decor? Who knows, might not be a good idea to ask that. Sena continue to help the Leader by removing some obstacle.
As night falls, Sena decide to take some rest after working all day with the Leader, on setting up this whole stage. But even he knows the work is not over. I see... the little guy is still here huh... For Sena, actually have another business aside from the ghost thing, and that is to lure out the watchful eyes, he knows who it is but decide to wait until finally the leader declare that one of them must lure the ghost here. Sena saw this the perfect chance to make the leader go away as he replies, "You go, I'll stay here for a look out." As Sena go look around the places.
-after the leader leaves-
Right after the Leader left, Sena decide to call for the one that have keeping an eye of him. "I know you're here. no worries, no one here beside me and this Noibat of mine." As he let Verna out of her ball, trying to earn the watchful eyes' trust. He had flashback to that one pokemon that stayed in the aquarium, the one that dislike human yes it's quite the cliche I know. After this aquarium was destroyed due to a Gyarados attack in the past, it decide to stay here waiting for someone or something.
