He may be taller, but Alec would lose every time in a physical contest, including if Richard promised to not use any blades and to tie one hand behind his back. He's too thin, and that skinniness is unaccompanied by any sort of wiry strength or knowledge of how to fight.

In short, yes, Richard could easily manhandle Alec through the window. The hardest part would be getting all of his gangling limbs past the frame without catching. The longer interpretation is that, if his shorter friend was capable of forcing him along, he certainly wasn't going to be any help with or challenge to the four men on the other side of the door.

Alec doesn't have to think about the longer interpretation. He simply knows, subconsciously. In his sharper hours, he would have recognized that the offer to be dramatic is another way of manhandling him. But, the wine. His only plan tonight had been to pour himself into bed and let the night do what it wanted.

If he goes with Richard, there's a chance the strangers will catch up to them in ones and twos, and he'll get to see a fight. The evening had been dull, and no one would dice with him. "Fine," he concedes, although he doesn't tend to be happy about it. "Maybe we'll both land headfirst. Maybe you'll fall into Marie's well, she won't like that."
