I think it's a little concerning that based upon the photos from the premiere event, they're going to have a hard time shooting anything from here out with Tom Taylor playing Jake. The kid has grown like a weed since they finished shooting. He's as tall as Matthew now and catching Idris quickly. I know studios can do a lot these days, but you can't stop time. Having said that, I'm sure anything played loosey goosey with the canon at this point will be written off or justified through the getting-old-quickly, get out of jail free card of "this being a continuation rather than an interpretation". Dangerous ground IMO but holding out hope.
