Senku would've preferred, if Roland had called out to him first or went for his arm instead. Roland could probably read his body language by the way he tensed when he was grabbed in the first place. "Hey!" He said, sounding more startled than for it to be a greeting, he'd been about to protest, shy away from his grip but Roland of all people was grabbing him with both hands, looking, well kind of manic.

"Hey!" He said, a bit firmer, trying to step back, but they're sort of in the doorway and there's nowhere to go. "Too close!" Senku retorted. "Let go!"

He hadn't raised his voice, but it was far from his usual level speech in return. He also didn't look like he was listening to Roland's questions and Roland's panic and he kind of couldn't at the moment, he was completely distracted by an overwhelming sense of feeling boxed in. He could address everything in a moment.
