Star Trek Discovery: Saints of Imperfection

Here are observations about the fifth episode of Star Trek Discovery this season, Saints of Imperfection.  There ARE a few minor spoilers below, but not full episode summaries.

1. May refers to transporting Tilly across the "dimensional plane."  So the thing Discovery is temporarily stuck in is basically an inter-dimensional portal.  Like a Stargate event horizon without the actual Stargate. Maybe THAT'S why the parts of the Discovery saucer need to rotate.  Because Stargates rotate in setting the destination address.  (In reality, CBS can't overtly use elements from MGM's Stargate, due to copyright, but the visual portrayals are reminiscent.)
2. Pike is seen entering the bridge from Lorca's Ready Room, even though Pike made a big thing a few episodes ago of not liking it and moving elsewhere. We can still see the stand-up desk through the doorway.
3. Pike and Georgiou were classmates at Starfleet Academy, although maybe not the same class year.
4. When Pike, Georgiou, and Burnham get into the turbolift, it starts going without anybody saying the destination.  In fact several times people get into the turbolift and don't say where they are going in this episode, but this is the only scene in which we see them continually after the doors shut.
5. A reference to "alligators" on Cestus III, was likely a reference to the Gorn, although supposedly Starfleet didn't know anything about the Gorn until the TOS episode Arena.  On the third hand, Lorca appeared to have a Gorn skeleton on display last season.
6. Also a reference to Deneva, one of the first Earth colonies, where Sam Kirk and family eventually live (and some of them die). 
7. Georgiou is eating an apple to show how cool she is, kind of like how the J.J. Abrams Kirk ate an apply in one of the movies.  She drops it when Burnham gets in her face.  She isn't as cocky as she pretends to be. Since they are getting ready to make a series about her, I HOPE that she is a nicer person than she lets on.  Here "oh look at the cute baby" moment last episode gives me some hope.
8. The new chief of security, Commander Nhan, is still wearing the skirt-and-tights version of the Starfleet uniform, except in Discovery blue.  Note that when Pike first came to Discovery, he identified her as an engineering staff member.  Now she's heading security.  Was she Security pretending to be Engineering, as a safety detail for Pike?
9. Once they find Tilly and...what else (spoiler) they find...they fritter away a LOT of time when they urgently need to be heading back.
10. Tyler has a radio integrated in his com badge, like TNG and later comm badges.  Nobody else has ever heard of that before, through the TOS movies.
11. The Section 31 ship does not have invisibility, but apparently is able to make its shields look like a big asteroid.
12. The tractor beams in this episode need a receptor or "tractor rig" to pull against.  The only time I remember the 1701 Prime using a tractor beam was in Space Seed, and they may well have placed a receptor on the Botany Bay, which we just didn't see.
13. Now we have two "we will meet again" foreshadows: Tilly and May, and Pike and Jacob (on New Eden). 
14. Leland is apparently in charge of Section 31, but he made a reference to "control" last week, and now we find out who "control" is.
