Sentinel and Claire, since he requested her assistance in talking down Tamara, because he didn't know much about the demon, but figured a familiar face would be helpful in this regard. His favorite situation was that she was fighting someone known as Azami, and they could eliminate the target they needed to eliminate in order to save the world. Then they could assist Tamara in defeating the true threat, a neutral scenario is the fact that someone pissed her off. She might be willing to be talked down, and see reason, perhaps reminding her about her duty to protect these worlds rather than destroy them.
Worst case scenario, she was actually the traitor of the group, and wanted to destroy the world for her own purpose. The android was not sure that Claire would be able to mentally handle facing one of her friends if he was honest. Granted, this scenario was only if there a way to get more information. He would request Claire's aid...when the situation was less dire or appeared to be less dire.
Then the android's thoughts shifted to his friends in Penecia, Sharaku, and Shunnosuke, he honestly hoped that they were okay and not involved in this fight. Lia too had better be safe so Maria could see her show again. One of his biggest concerns he had was the safety of his friends. The android just hoped that they were safe, he knew they were powerful, but if they were somehow wrapped up in Tamara's fight, he prayed for their safety and that they could hold out until he got there to help them!
