Guysbert was supposed to be married with Bean, but when she disagreed to be wed with an outburst of anger, Guysbert's head was impaled on some nearby decor. This didn't in fact kill him, becoming a running gag for the rest off the season.
In To Thine Own Elf Be True, a callback to his near fatal wounding in the first episode sees him used as a test subject for the Elixir of life. After initial success, as the Exilir failed, he died as his brain fell out of his head and subsequently stabbed himself with the sword.
- If his wedding to Bean been a success, he would have taken her back to Bentwood with him and the plot of Disenchantment would have been unlikely to unfold.
- He seems to be the opposite of his younger brother/cousin in terms of personality since Guysbert is dim-witted but nice to Bean while Merkimer is smarter and doesn't care at all about Bean.
- It is implied that he may have liked Bean since he didn't seem to have a problem with being forced to marry her and when they meet again shortly before his death he says that the possibility of gazing upon Bean's face kept him alive (along with the rotten food he had been eating).
