Death Note: The Musical is coming to London this summer, which is pretty exciting news if you're me!

'Wow, is Riona posting an entry about something that's not The Goes Wrong Show?' - bad news, I'm afraid.

Tem: Are you looking forward to seeing your boy Light Yagami?
Rei: Played by Robert Grove.
Riona: That would be a bold casting decision, but I'd watch it.
Tem: Death Note Goes Wrong. Their 'prop Death Note' is an actual Death Note. They need to write in it during the show, so they just use the names of the people who bought tickets. At the end, they're going 'wow, this was our most successful performance ever, can't wait for the applause,' and the lights go up to reveal the entire audience dead, with Ryuk sitting in the front row and applauding.
Rei: They consider writing Jonathan's name in the Death Note, because it's the only way he'll be included in the play, but they decide against it because he's not part of the audience. That's the only reason he survives.
Riona: Or they write his name in the Death Note, but he survives because they misspell it.

Robert Grove also cannot be entrusted with a Death Note if he knows it's real, of course. If Robert sees an opportunity to secure the role he desires, he will take that opportunity immediately and think about it later, if at all.

Basically, Robert has no particular desire for anyone's death, but he will one hundred percent kill people if it's a straightforward way to get what he wants. I give it a week before he kills Chris in order to get the lead role and then goes '...hmm, I might regret that later.'

Dennis might actually be the safest member of the Cornley Drama Society to entrust with a Death Note. He wouldn't use it with the intention of killing anyone. He would almost certainly forget it kills people and start using it like a normal notebook, which is risky, but if he writes anyone's name he's probably going to misspell it.

Aaaaand then Robert would wrestle the notebook off him and use it to kill Chris so he can have the lead. Let's just not give the Cornley Drama Society a Death Note at all.
