Despite their rivalry and antagonistic relationship, Beerus does genuinely care for Champa. That was made obvious at the conclusion of the Universe 6 vs. Universe 7 tournament.
Beerus (ビルス, Birusu) is an instrumental god in the 7th Universe, he is the Hakaishin of his respective universe. Beerus' role in his respective universe is to maintain the balance of the universe by destroying planets, in contrast to its Kaiōshin who preserves them.
Super Shenron was, however, the only known being capable of bringing back beings erased by Zeno, as he effortlessly restored all the erased universes, indicating his power probably doesn't fall too far behind Zeno's.
Though Whis is mostly indifferent to Beerus' actions, it is clear that working together for so long has led the two to have some kind of rapport with each other. There are times when their relationship seems more friendly than professional.
He just lost his brother and is being focused on by the camera. Beerus obviously being conflicted with how he felt probably wanted to be left alone (audiences eyes off him) and out of the spotlight and as OP says thats why he says "say something" because he's telling the narrator to hurry it up.
While Whis had said that Goku and Vegeta were strong enough to be on par with Beerus if they fought as a team (which implies that Vegito is stronger than Beerus), Akira Toriyama stated that Beerus was the strongest in the universe (other than Whis.)
Beerus also had a supporting role in Ressurection F, the follow-up Dragon Ball film. For example, did you know that Beerus wasn't born into divinity? Unlike the Kai or Supreme Kai, who were born with godly ki and were destined to be deities, Beerus earned his position as a destroyer.
The only time Beerus died was in the dragon ball super future trunks saga. Pretty much in the alternate time line Goku and Vegeta has whis and Beerus with them. In that timeline Zamasu had killed the Kais. In order for the gods of destruction and the angels to exist, the Kais have to be living.
Eventually, Goku, with the help of the other Saiyans, transforms into the Super Saiyan God and fights Beerus, just to be defeated by the God of Destruction.
Goku (Battle of Gods Saga) After gathering the energy of 5 pure hearted Saiyans and becoming a God. Goku is able to fight Beerus while he is using 70% of his power. Goku admits that he was holding back at first only using 80% of his real power which would put Goku's battle power at 4.8 Quadrillion.
We see at the beginning of the Anime that SSJ4 Goku and SSJB Goku are evenly matched and in the Manga, SSJB Goku is stronger than SSJ4 Goku showing that no matter what SSJ4 should be equal or weaker. This would mean SSJ4 Vegito is equal to SSJB Vegito but weaker than SSJBKK Vegito.
