Marceline flew straight to the window. She didn't want to deal with the banana guards. Bubblegum had never liked her coming to her room unannounced, but Marceline didn't care tonight.
Marceline knocked on the window. This clearly startled Bubblegum. "Go away, whoever you are. Come to the door tomorrow morning." Marceline tried to reply, but couldn't get any words out, so she knocked again. Bubblegum came to the window and saw Marceline with tears in her eyes and opened the door.
"Marceline, what are you—"
"He became Simon again," Marceline explained, trying not to cry. "He reverted back to Simon and then we had to use Hambo to open a portal and Betty came through and now she's dead and he's Ice King again and I just...I just can't keep going on like this," she stammered. She moved directly in front of Bubblegum. "Simon found Betty again after a thousand years and they lost each other just as quickly again. And I lost someone I love again. Please," Marceline broke down sobbing. "Please...can we be us again?" She fell to her knees, almost begging.
There was a tap at the window. "Princess! Do you need assistance?" a Gumball Guardian bellowed.
Bubblegum wrenched the curtains open. "No! Leave me alone for the night," she shouted curtly.
Marceline had regained some control, though she hadn't gotten up. Bubblegum knelt beside her.
"I can't promise I can do this, Marceline. I can't promise we can do this. I can't promise our history won't repeat. I'm scared we can't. But my Glob, I think we have to. We owe it to each other and to ourselves to try again." Marceline looked up at her, hardly believing this moment had finally arrived. Bubblegum nodded her head. Marceline fell into an embrace with her, the tears reappearing.
Bubblegum pulled away slightly. "Don't cry, my love," she said and lifted Marceline's chin so their lips could meet.
Bubblegum's mind was screaming all the reasons why they had not and could not stay together and why they had had to stay away. The moment their mouths brushed together, those voices were silenced for good.
