I wondered how exactly Smitty was doing that 'bam' effect. Then I remembered that he has a small control over probability.

Then I also theorised that it could be that they're just that much in-sync with each other. : )

Then I remembered that this is a webcomic in which a girl fights a robot with a broadsword and telepathy so that she can learn to fight a ghost made out of white-hot rage so that two other girls can rescue an impaled elf-skeleton from a river surrounding a castle in which kids are taught how to deal with super technology and magic.

So I got over it.
