If I use a different part of the verb it still counts, right?

interrogate

"Where the hell have you been?!" Merlin had barely stepped through the door when Arthur ambushed him.

"Please don't, Arthur," said Merlin wearily, slumping into a chair, exhausted. "I'm not in the mood to be interrogated." Arthur growled in anger.

"Well that's just too bad for you then, Merlin!" he barked. "You were gone for hours! I had to get my own dinner, and if I find out you were in the tavern again, so help me..."

Merlin let Arthur's harsh words wash over him. He tried to stay calm, to not shout back, to exercise restraint like Gaius always told him to... But he was bone-tired, and aching from yet another magical encounter with yet another evil creature trying to destroy/kill Camelot/Arthur.

He wanted to stand up and yell, "I was saving your life, again!" He wanted to confide in Arthur. He wanted to tell his best friend everything.

But he couldn't. So he held his tongue, and let Arthur shout at him, and wished he could sleep forever.
