[It admittedly takes a moment for the comment to register, leaving Sirius there to gape dumbly at Tony as it processes, but when it hits him he stands up so quickly and with such force he almost loses his balance.]

Wait, this is mine?

[His eyes light up with excitement, bright and boyish and absolutely impish before he gives a laugh of disbelief.]

Hold on a mo', this is mine, that's what you're saying? You made this and you're giving it to me?

[Before Tony can escape Sirius ends up throwing himself at the man, embracing him with a vice-like hug, topped with a dramatically loud kiss planted on his cheek.]

Have I told you how much I adore you? Because I adore. A true bloody hero if there ever was one.

[And his attention is back on the bike - his bike - and then back on Lydia with a beaming face.]

Two hours and I can pick you up. Are you in?
