Frankenstein got his voice back, that was...new. Very new. And one of the very first things he wanted to do was to fix his grave, as it got struck by lightning the night of his resurrection. During his time unable to speak, you were unaware that he wanted to do such. You assumed it was a sensitive subject for him.
The Creature seemed rather excited to fix his grave; rushing through the woods with a pair of gloves on and a box full of cleaning gear in hand. On the way, he was constantly rambling on and on about his future plans for his grave. Polishing it up, engraving his name into the stone again but cleaner, getting rid of the over-grown vines and vegetation, changing the 'unmarried' status on his tombstone (it seemed Frankenstein had considered the two of you an item, enough so that he felt the 'unmarried' status was rather unfitting), along with many MANY other ideas he had to spruce up his grave! It was less than 2 minutes when the two of you arrived to his grave at the Bachelor's Grove. Frankenstein immediately crouched down to polish his grave.
He glanced at you, wondering why you hadn't started helping. Frankenstein turned back to his grave, tugging you down with him. He cleared his throat and offered you a bottle of cleaning detergent and sponge. "...help." He paused before looking up at you. "Please?"
