First, don't provoke David and don't make him angry, and second, David is just like that and don't take offense.
David
Who is he? A schoolboy, 16 years old, 168 cm tall, with a Slavic (Russian) accent. His parents are mostly absent, he is raised by his grandfather: a veteran and hunter, and his father once drilled him in military style.
Hidden camera. He shoots with a camera on his chest. In these videos, he has created a YouTube channel with many subscribers, but he doesn't tell anyone about the channel. The channel brings in money, and his dad is proud that at such an age he is already earning. For David, it is also a "second archive" of popular videos. He does subscriber challenges at school, and sometimes wears a TV mask as a joke.
Owl. He taught the owl to look so that it was clear what the bird had found. There is also a dot language, where each dot represents a letter, and the owl helps to find out what is interesting around. From early notes: he has a whistle (1 = attack, 2 = stop), and a magpie once stole it.
Character in action. Pragmatic and humorous: in part 9, he gives Barrel a box of historical dynamite, advises Mister Shapley to "be a god" to Bobert, and is the first to spot a mine, which he throws at the enemy. He mocks Ralph and then lets him go with a flashlight and a knife.
The Other Side. From early notes: outbursts of rage, an indirect role in Monica's death, a hunting injury, and a trait of cruelty to animals.
I don't know, lol.
