He could Spin for Kings and Queens
Rumple stood there for a moment looking at Wish Realm Hook. "What is he going to do next?" Was what Hook had asked.
"What Rumplestiltskin does best! Spin, spin spin." He said walking away as he continued to repeat 'spin, spin, spin.'
As Rumplestiltskin sat down at his spinning wheel he kept repeating "Spin, spin, spin." He repeated it so he wouldn't stop spinning the straw. As he spun the straw it was so he couldn't forget the memories. The memories of everyone he knew now that he had lost the battle to his darkness. He didn't want to lose control to them to where he was gone forever. He knew Belle was right that no matter how long his journey would be he would be eventually reunited with her. So he spun and spun because he didn't want to forget her, no matter how painful it was to remember her.
Rumplestiltskin reached for more straw to spin he sighed upon seeing the basket empty. He got up from his stool and repeated to himself "straw, need more straw."
As he went and got more straw he started to slowly slip away into the darkness. He stood there looking at the stack of straw only to be pulled back to reality upon a knock at his door.
"Come in, come in!" Rumple yelled as he made all the straw appear beside his spinning wheel. As Rumple walked back to the spinning wheel he stopped in his tracks upon seeing Alice. 'How long had it been since he had last seen her? Days? Weeks? Months?' He couldn't remember which scared him. He ran back to the spinning wheel and started to spin again as Alice talked away.
