Bruce still exists but is heavily influenced by Kara's mannerisms/thoughts.

"S-something's not right..."

Bruce fought against the tidal wave of subliminal messaging, struggling to so much as raise her hand to pause the lesson. She cringed internally, bringing her hand slowly towards the interface.

~What are you doing, Kara?~ ~Good girls complete their training, Kara!~ ~Don't you want to be a good girl, Kara?~ ~Finish your training, Kara!~ ~Be a good girl, Kara! ~Stop fighting it, Kara!~ ~You're not a man, Kara!~ ~You're prolonging the inevitable, Kara!~ ~Succumb, Kara!~

"GYugh!"

Bruce huffed in Kara's feminine tone, inhaling and exhaling sharply until she finally managed to smash her fist into the screen. Silence followed as she steadied her breath. That was it. She stopped it! That was way too close for comfort. She was lucky she caught on to what the lesson was doing before it was too late. That wasn't an English lesson at all! Damn thing was trying to brainwash her. She now had reason to believe that every single piece of Kryptonian tech in Superman's fortress could potentially be infected with some kind of virus, one hellbent on turning her into Kara Zor-El, inside and out.

Only thanks to Bruce's years of mental training and sheer **** of will did she manage to not lose herself to the alien programming. However, even though the English lesson ceased, she still felt the presence of the hidden suggestions. She saw her reflection in the cracked glass. Somehow, she didn't see the face staring back at her as someone else's, but as her own.

"I have to get out of here..."

Bruce figured, running a hand through her blonde hair. Easier said than done. The Fortress of Solitude was one of the most secure facilities on Earth. There was no entry or exit unless Superman allowed it. She pondered her options as she stared at herself.

~That's you, Kara!~

Bruce snapped, turning her back to the monitor.

"Who said that?"

Her eyes darted around the room. Nothing had changed since she set foot inside the quarters Kal had prepared for her.

~We're your conscience, Kara!~ ~We're in your head now, Kara!~ ~We'll make sure you act right, Kara!~ ~Like a good Kryptonian girl, Kara!~

A cacophony of tones echoed in her mind, all distinctly Kara's voice. Her voice.

"Stop! Get out of my head!"

Bruce screamed, contorting her face and tugging at her luscious blonde locks.

~Such a strong will, Kara!~ ~You will make an excellent Supergirl, Kara!~ ~No more being Batman, Kara!~ ~Batman is edgy and lame, Kara!~ ~Pretty girls have more fun, Kara!~ ~Save the day with a smile, Kara!~ ~No escaping the inevitable, Kara!~

"I SAID STOP!"

Bruce slammed her head into the monitor over and over again. She raged against her mind being drowned in a sea of bubbly pink thoughts.

KNOCK KNOCK!

"Kara? Are you okay in there?"

Bruce ~No, Kara!~ heard Clark's ~No, Kal's!~ voice on the other side. She desperately needed his help, as much as it pained her to admit it. She opened the door, meeting his gaze as she parted her lips, internally forcing herself to eek out the words. Yet on the surface all she did was give him a bright eyed smile and said:

"~I'm great, Kal! Thanks for checking on me! I just slipped is all!~"

What? That wasn't what she wanted to say!

"Oh, okay. Well, I'll see you in the morning, then!"

Kal smiled back and nodded, turning and floating away.

"~Goodnight, cousin!~"

She called after him, to which he waved. Bruce (Kara?) closed the door, turning to the empty space in the room.

"This is all wrong..." Kara muttered. Wait... did she just think of herself as... Kara?

"~What am I saying?! This is all right! I can't wait to go shopping with my cousin tomorrow!~"

~Kara~ perked up against her will. Slowly, the wheel was being wrestled away from her. It was starting with her speech, but who knew what else was next if she allowed this ~lovely gift~ to progress further?
