What do you call a person who calls his eternal master, a bastard

At the tree, Butler Mo was standing with the team leader as both of them were staring hard at the golden hilt.

"How uncommon."

The team leader spoke while marveling at the artistic beauty that was emanating from the hilt's gold color while there was no sign of any art carved on the hilt. That's how mysterious just the hilt that was stuck at the center of the lower part of the tree, was.

"Uncommon indeed. If it was a fruit, then that would have still been understandable since the birth of fruit is part of a  fruit tree's life." 

Butler Mo started talking like a philosopher while the team leader looked at him with wide eyes.

"A fruit in the middle of a tree's trunk...."

'What a stupid pig.'

He cursed at Butler Mo and moved backward.

  While staring at it, Butler Mo also stepped back.
