Quick note, I think the magician is Servant? Correct me if Im wrong and I'll correct it.

Robbie pointed at Servant.
"It wasn't me! It was him!" He yelled. The magician looked at him in shock.
"Me? It was you! I saw you!"
"And I saw you!"
They both huffed and crossed their arms, turning away from each other. Emma came forwards, her arms also crossed.
"You two need to spill the beans before I bring Martha here. Trust me, she won't hesitate to shoot."
They both visibly gulped but neither said a word. Emma raised a brow.
"If you guys don't say anything in the next ten seconds, I'll call her here."
Again, no response.
Emma sighed.
"Fine. 10, 9, 8, 7, 6,"
Robbie turned to look at Servant.
"5"
Servant connected gazes.
"4"
Robbie tilted his head questioningly.
"3"
Servant slowly nodded.
"2"
They both breathed in deeply, preparing themselves.
"1..!"
"We ate the cake!" They yelled in unison. Emma smiled.
"I knew you'd fess up."
Robbie sighed.
"We were hungry! So when everyone was celebrating, we set off some fireworks and then we got the cake a-and we hid in some random place and we, we... we ate the cake an, and.. then.. it was really, like, really yummy— delicious and Uhm I don't really regret it... Uhm,m" Robbie trailed off.
"I'm sorry!" They yelled in unison, tears streaming down their faces. Emma petted them both on the head.
"It's alright guys. Just include me next time." She winked. They both laughed and wiped their tears away.
"Okay!"
