You return to the manor, walk through the stone corridor leading to the Batcave, and faintly hear a retching sound. The bathroom door at the end of the Batcave is ajar, and there are a few drops of water on the white porcelain floor. You push the door open and see your omega partner Bruce Wayne curled up next to the sink, one hand on the ground, a thin sweat on the corner of his forehead, and the other hand tightly grasping something, which you can't see clearly. His face is so pale that it is almost transparent. When he looks up, his blue eyes are full of surprise.

"Why... are you back?" Bruce's voice is hoarse, so low that it seems to have been swallowed by the night.

You didn't answer, but walked forward and squatted. Your sight just happened to meet the slightly raised curve on his chest - it was not muscle, nor was it an ordinary glandular swelling, but the slightly congested mammary gland that Bruce deliberately covered with compression underwear. His clothes were soaked with sweat and stuck to his skin, and the unnatural swelling couldn't be clearer.

"Bruce." It was the first time you called your omega in such a low voice.

He turned his head away, as if he didn't want you to see his current appearance. But his hand never relaxed. He held a test strip between his fingers. It was an Omega pregnancy early screening device used in private medical equipment. Two red lines were clearly shown on it, as dazzling as an alarm.

You took the test strip between his fingers and said nothing, but just gently squeezed his cold hand.

Bruce seemed to have finally taken off the last layer of disguise. He trembled slightly and his shoulders shrank imperceptibly. His voice was so low that it was almost inaudible:

"Pregnancy... is not part of the plan."
