Could be anything of course (not even DW related) and John is just teasing fans.”
After Barrowman's recent outbursts towards Moffat I doubted whether or not Jack would appear again, but whose to say it isn't all water under the bridge and everything is fine?
I wished a few years ago (and repeatedly ever since) that whenever Moffat left Doctor Who, he'd go with a big timey-wimey angels story that could incorporate a lot of his signature characters. It remains wishful thinking right now, but I'm going to convince myself that this is actually what we're getting. The mysterious 'arrival' referred to in Class turns out to be the story arc for Series 10 of Doctor Who, with the angels having a big plot at the end of the series. Said story could also see the return of Captain Jack in some capacity (these small hints might amount to nothing, but again I'll convince myself otherwise), it could see the cast of Class crossover into the main show in some capacity (there was that unresolved speculation that Fady Elsayed was to appear in Series 10, he also posted a picture of himself with a Tardis today funnily enough), you could involve Missy somewhere along the line, then Osgood/Kate, maybe even make use of the Doctor's daughter wildcard. An assemblage of characters, a little like Series 4, but not necessarily aiming to get them all into the same room so much as having the Doctor make use of his various connections to overcome a massive threat.
Wishful thinking... convincing myself this is happening until filming/announcements prove otherwise and it turns out the finale is all about Nardole being Emperor of All Existence or something
