Careful wording there, since Patrick has seen the Rabbit with her previous Master, as will be confirmed in chapter 14.
Apparently when you search “Doctor Who scarf” on shopping sites these days, most of the results are “some kind of blue scarf with a TARDIS on it.” Which are cool, I’d wear one, but — come on, is the classic Fourth Doctor “commissioned for the show and the props director didn’t say when to stop knitting” scarf no longer iconic enough to be commercially-viable?
That’s the only one Sparrow would settle for, at least. Seen here, in the bottom left panel, maybe a few hundred pages before she ever actually wears it.
Bianca: You’re not allowed to interrogate Patrick until we’re safely home, got it?
Sparrow: Fine. But he better have something good to say! Because I’ve never heard of a Being picking a fight at a crowded club before.
(ZOOM, rumble rumble)
Sparrow: What was that all about, huh?!
Bianca: And do it without yelling!
Patrick: I don’t have to answer to you.
Bianca: But you have to answer me, right? Well, I’m asking! Could they have been looking for you?
Patrick: I’ve never seen the Rabbit with that Master before.
That doesn’t mean he couldn’t have heard of me! What with how I’m a world-class fighter, and all.
But it seems more likely they agreed to have a battle with the other Master, then decided to make a show of it.
Bianca: How would they have found each other?
Patrick: Craigslist?
There are knitting patterns for that scarf
My ex made one, back when we were married.
Fun fact, through the filming of all of the episodes, the scarf got damaged numerous times. As such, the scarf isn’t always the same length, and the fourth Doctor actually had several scarves over the years, as it would get short enough people could notice the difference.
Because of this, and also because not everyone is up for the same knitting challenge level, there are actually multiple distinctly different patterns for that scarf, at various lengths that the fourth Doctor’s scarves had been on shows.
To be clear, they’re all ridiculously long and incredible endurance challenges for beginning knitters, just some are more so than others. No, it’s not something a beginning knitter could make in one sitting, but learning how to put ones work down and carry it around without having it unravel on one is not trivial.
If I recall correctly, she went with one of the middle lengths, and took something like six months to finish it. Admittedly, she opted for an additional level of starting and stopping challenge than she could have, as she took it to meetings where she was the person taking the meeting minutes, and worked on it in said meetings.
