A/N: This book has surpassed 200k reads! You guys, I have no idea how to thank you! So all I can do is say...THANK YOU SO MUCH! I had no idea this book would get this popular, and you all are responsible for it. This imagine will be part of a little series that I've been wanting to do for a while but haven't had time. Now, I'm gonna make time! Enjoy!

P.S. Also, what would you all think of a Steve + Bucky imagines book? Maybe after this one reaches the WP chapter limit (200)? I was thinking about calling it 500 Words or something, make it a bit longer. Whatcha think? Yes? No? You guys will decide ;)

You flip through the pages of the spellbook Stephen Strange had given you earlier. "You need to hone your magical skills," he'd said, handing you the big, leather-bound book. "Try using this. I've marked some beginner spells with sticky notes. But whatever you do." He leaned in closely, staring straight into your eyes. "Don't do the spell marked in red."

So, naturally, you flip straight to the forbidden spell, the one marked in Stephen's sloppy doctor handwriting. "DO NOT ATTEMPT. EVER!"

You skim the spell, seeing the words revolve around youth and energy. You scoff. "This reads more like a face mask than a spell, Strange. What were you so afraid of?"

Ignoring the warnings, you chant the spell. When you finish, nothing happens.

At first.

A knock on your door causes you to flip the book closed and wave a hand to magically open the door. The knob turns on its own, and you see your boyfriend on the other side. Bucky smiles widely at you, and you return the expression

"Whatcha doin', [Y/n]?" he inquires.

You shrug, motioning to the spellbook on the bed. "Trying out some new spells that I got from Stephen--"

You're cut off by the spellbook glowing brightly. It shivers in your hand, and you shove it away. "What the hell?" Bucky mutters. "What did you do?"

"Just a spell that didn't work!" you reply as the book glows brighter.

Bucky grabs your hand and pulls you for the doorway. You close it behind you, and the two of you run for the elevator. As the doors open, you turn behind you and see a wave of blue energy pulsing through the Tower.

And it's heading straight for you.

"Bucky!"

Bucky follows your eyes, then shoves you into the elevator. "FRIDAY, lock it down!"

The AI agrees, then shuts the metal doors in front of you. The elevator goes into lock-down, and you feel the wave pass over the metal box. Somehow, FRIDAY protected you.

"Open the damn doors!" you shout.

The doors open at your command, but you don't see Bucky when they do. Then you hear a whimper. When you look down, your mouth hangs open at what you see.

A dark-haired, blue-eyed two-year-old with a little metal arm.
