Cassandra Cain had faced assassins, mercenaries, and Gotham’s worst criminals. But none of that compared to babysitting Bruce Wayne and Selina Kyle’s two-week-old daughter.

You.

Currently, you were bundled up in a tiny black onesie, peacefully sleeping in your crib. Cass sat nearby, perched in the shadows like a true Bat, watching you with careful eyes.

Easy. Too easy.

And then… you stirred.

Cass immediately tensed.

Mission failure imminent.

Your tiny fists clenched. A whimper escaped your lips. Cass’s eyes widened. She knew what was coming next.

You began to cry.

Cass froze. She had fought League assassins without breaking a sweat, but this? A crying baby?!

Frantically, she reached for the baby manual Barbara had given her. She flipped through the pages with ninja speed.

“Hunger? Diaper? Cold? Evil possession?” she muttered.

She picked you up awkwardly, like a tiny, fragile piece of evidence. You squirmed, your tiny blue eyes staring up at her. Cass hesitated—then gently pressed you against her chest.

Your cries slowed.

Cass blinked.

She started rocking you carefully. You yawned, curling against her warmth, little fingers gripping the fabric of her shirt. A tiny, satisfied sigh escaped you as you fell back asleep.

Cass exhaled.

Mission success.

She smirked to herself. “I win.”

At that moment, the baby monitor crackled, and Alfred’s amused voice came through. “Well done, Miss Cassandra. Perhaps we should add ‘Gotham’s Best Babysitter’ to your list of titles?”

Cass rolled her eyes. But when she looked down at you, peacefully nestled in her arms, she couldn’t help but smile.
