Calvin shrieks, which he's going to regret later, but it's the only reasonable reaction to being dragged into the bushes after thinking your brother might be in danger. There's a split second where his instincts anticipate an immediate (but painful) death. Even after being safely caught in Dimi's arms, that yelp becomes a string of angry curses as Calvin shoves his brother back. Pointless, since they're already lying in the dirt and grass, twigs and branches scratching them up. Dimi's laughter and Calvin's blustery temper can be heard over the camp noises, making it crystal clear no one's actually hurt.

"You're a real arse, you know that?!" Calvin hits Dimi's chest again for good measure, but there's not much force behind it.
