Personally

You will the chamber to grow more and more. Soon it's big enough for two. The skin splits open to welcome you as you gently lead Evelyn within. As the chamber seals again and liquid begins to pool in you once again turn your thoughts to Evelyn's mind. You remove your strict control over her, instead you return to your previous method of controlling her. You tap into her dark thoughts, her forbidden desires and bring them to the front of her personality. You make her desire you on every level and join you in the wonderful new existence you offer her. As you manipulate her mind you feel that sense of kinship with her grow, she's not so different from you before your rebirth. Feelings of worthlessness, a desire to belong, dark fantasies she would never admit to - it only seems right you give her what has been given to you.

As she awakens from her trance she throws herself towards you through the liquid you are both now submerged in. You feel her desires blasting into your mind, you may have pushed her along this path but now she embraces it. Tendrils emerge and pierce into her body, she moans in pleasure as they do. As a particularly large one inserts itself into her sex you take the opportunity to stimulate her, groping her ample breasts. The chamber begins it's work, pumping the fluids and microbes that will convert Evelyn from her frail human form into one of glorious alien perfection. Already you feel her body beginning to change, your minds connecting on an even more intimate level as she is drawn into the shared consciousness of the swarm.

Of course she will retain her individuality like you, although her personality may need to be tweaked for her new role. And as the swarm's queen that role, and her very being, will be shaped by your will. You focus on her, seeing the station in the swarm she will assume...
