[Sebastian's own clothes are more practical in this weather, of course - he's not wearing a jacket (but he's carrying a bundle of some kind of fabric one on arm? maybe he took his jacket off?), meaning the only thing the wind has to grab are the tails of his suit. His pace is calm and unhurried even after she calls out to him - he lifts his head, clearly showing he notices her, although he doesn't otherwise responds, nor waves. Only once he's close enough to be heard without having to yell does he answer.]
I apologise if you had to wait. [What, five minutes?] You are all right still?
