There was a flurry of action as Sirius actually grabbed his father and turned the sofa into a Teddy sandwich. Good Lord, he hadn't been expecting that and it showed on his face. Though he did appreciate the closeness of Sirius, he didn't actually want Remus to be uncomfortable. The situation was... Unusual and Remus was in his right to want space or to not even speak to Teddy at all. It wouldn't make him feel good but who was he to force those interactions?
He was very happy to lean against Sirius as Remus took over the conversation, explaining his - well, not hesitance but near enough. "Funnily enough, I was going to say some of those same things but from the reverse point," Teddy offered, smiling a bit lopsidedly at Remus, "And also that I can call you Remus instead if that would make things easier for you." He paused for a moment, worrying the inside of his bottom lip for a moment. Whatever he had been thinking about saying, he shelved it for another time and instead reached out for Remus.
"Come on then, let's make it a proper snuggle puddle. If need be, I can build us a pillow fort," he had a feeling that Sirius, at the very least, would be quite enthused about that idea. But his attention turned to Sirius then and he pointed a finger at the other, "We are never going to get to what the Hell is going on at this rate and it's entirely your fault." Then he lightly booped Sirius on the nose.
