The servant had believed, for a brief moment, that he might have survived seeing the things that he shouldn't have seen. But when he saw a claw coming out of his chest, he realized that the reality was quite different.
He had seen Jenia being embarrassed by an outsider. She couldn't let him live to tell the others that she was played by an outsider. She had to kill him and that's what she did when Estelia wasn't here to see it.
After she killed the servant, she dragged her corpse away from the place, ensuring that not even a single drop of blood was left behind.
Inside the room, Estelia was focused on the stage, waiting for the auction to begin. She didn't care about other things, but Eren was different from her.
More than the stage, she was interested in the surroundings. His divine consciousness had spread out, to observe the other rooms.
