Raphael's mind awoke. Thoughts filled it: How he met Mona Lisa, how he could trust her, how beautiful she was-
'Am I going soft!?' Raph exclaimed in his mind. 'Who cares. I'm finally awake!' Raphael's eyes finally awoke. He looked around Donnie's lab. To the left, he sees Jamie soundly sleeping still. 'Still? Man I feel bad!' Mona's bed next to Raph was empty. He rested his head against his pillow and closed his eyes, then reopened them.
"Mona!" The monitor connected to him beeped faster.
"Donnie! Raph's monitor!" Leo's voice echoed.
"Aw shoot!" Donatello ran to his lab. Seeing that Mona was gone, he tried to calm Raphael down. "Raph! It's OK!" His voice shook, not knowing what to do.
Raphael started to hyperventilate. "Ahh! What do I do!?" Donnie exclaims, holding his head.
'D-Did something happen to her? Who hurt her!?' Raphael screamed in thought. Thinking the worst.
"Mona Lisa!" Donnie screamed at the top of his lungs, realizing that she was the answer.
Mona ran into the room. Alright and unharmed. She gasps as she saw Raph's uncontrollable breathing. Mona ran to him and kissed him on the lips once again.
Raphael calmed down as soon as their lips touched. Donnie smiled and sighed in relief of the fact that he knew his brother was alright now.

Mona took Master Splinter's word of advice: to heal her spirit with Raphael. It may be the only way to officially heal him. Once and for all. Even with Doer gone, Raph still has negative impact. He doesn't remember him at all, but the events haunt him.
She took a chair and pushed it against. Raphael's bed. Remembering a Christmas with her family, she remembered a gift her sister gave her before never seeing her again. It helps save loved ones, playing the right song. You'll know they're a loved one if they glow while you play it. She rubbed her soft hand against his bandaged hand and ran to the surface, without letting Donatello ask why.

Mona Lisa came back to the lair with a small round instrument. She knew a song her father has taught her on it.
"Is that-?" Donnie began, but she started playing.
Raphael started to glow, and so did Mona. Little did they know, Jamie was glowing too.
