The female Nanjorian steps aside, and a pod emerges from the wall in front of him, looking weirdly fleshy and soft, like a giant fruit, and it openes up at its middle, the inside looking kinda like a peach with the stone carved out. Ben had to admit, it looked weirdly enticing to him, like he could just step inside and rest there.
The male Nanjorian turns to him and addresses him, the drone again acting to translate for him. "Your new station will be assigned to you once you have been reborn as a Nanjorian and brought into our society. Don't worry, the experience is totally painless." Ben isn't sure he believes that, but he doesn't wanna risk getting on these aliens' bad sides. So he walks into the pod until he's standing inside it. He hears the Nanjorians press some buttons, and the pod closes around him.
For a moment, there is darkness, but then a light illuminates above him, allowing him to see inside the pod. To his surprise, it feels oddly comforting being inside this thing. Even though he doesn't consciously realize it, the pod was made to have similar conditions to the human womb, prying the mind into a pliable state.
The liquid dissolves his clothes, and he starts to float in it, not needing to breathe in the comfortable environment to stay alive. The insecurity and fear rapidly fades from Ben's mind, and he enters a dreamlike state- still conscious, but contented, hazy, unwavered by anything weird around him.
But the liquid is doing more than sedate and incubate Ben. It contained invasive cells which seeped into the body so the human can be reconfigured, and with Ben's body's defenses down, its effects are rapidly starting to show.
