You won't need to bump here. It's a very slow forum.
Singing Seraph
You don't kill the comedy relief. That is a big no-no.
Why not? Life doesn't care if you're witty or silly - if you hang around a giant space battle between two massive fleets, there's always a chance you could take an arrow to the knee, or a spike to the chest. If being funny gave a character some sort of immunity to danger, it would kinda ruin the tension and suspense, wouldn't it?
Infinite Space did this perfectly. Characters died. Sometimes they were assholes who'd been doing horrible things to you and your crew. Other times they were friends, and allies. One of the most emotionally charged scenes in that game is where an important character dies trying to save the main character. This individual had been fighting along side you for most of the Second Act, and he/she (I don't want to spoil it, if you've played it, you'll know who I'm talking about. If not, I'll keep it as vague as I can) brought a lot of light hearted fun to what would have been an otherwise dark and depressing chapter. His/Her death showed that the upcoming conflict was big, and that none of the main characters were safe.
