Observations in TNG: "Evolution"

The small box in the foreground of this shot will be seen again in "True Q".

Green transparent PADDs with LCARS buttons have appeared before, namely in "Pen Pals". They would go on to be seen on TNG until the end of the show.

The probe dubbed "The Egg" is a re-use of the containment unit from "The Child". Most of the open areas of the unit's external structure were filled with panels, some transparent.

There is a red light effect outside the shuttlebay door already before the door opens and we see the very red, very close red giant outside. Great cinematography!

Another good look at "The Egg" and the new shuttlebay control booth. The comparison screenshot from "Time Squared" shows what the set looked like in season 2. The lateral door is now painted in a darker shade of gray, and the console is gone.

The rear wall of the control booth features an LCARS display with a manifest of all shuttles and shuttlepods.

Also, notice that the shuttlebay doors of shuttlebay 2 are fully open, yet in the following shot of the USS Enterprise-D drifting towards the red giant, the shuttlebay doors are closed.

The carpet patch is not visible in TNG-R.

Note that the effect on the screen consists of many swirls in TNG-R.

Doctor Crusher's medkit in season 1 often featured a 1980's digital thermometer as a PADD stylus or medical tool. As soon as Dr. Crusher returns in season 3, the anachronistic device is back as well.

It is hard to resist the temptation to caption this with a Uranus joke.

The sickbay replicator was added to the set between seasons 2 and 3.

When the close-up of the replicator is shown, a red liquid is pouring from the full, blue glass. In the shot showing Crusher standing next to the replicator, however, only the empty blue glass can be seen.

Another look at the medical lab set. This is the wall adjacent to the waiting area in front of Doctor Crusher's sickbay office. The monitor on the desk was first seen during Data's psychotropic stability examination in "The Schizoid Man". It also appeared in sickbay in "Shades of Gray".

The large transparent block with red circuits inside was usually seen in Data's quarters and sickbay in seasons 1 and 2. They often appear in the sickbay office in later seasons. The green and blue varieties of this block are later seen in Dr. Stubbs's guest quarters. They first appeared in the Federation Council in "Star Trek: The Voyage Home".

This unique microscope is seen again later in this season in Marla Aster's house in "The Bonding".

The device Wesley Crusher uses to investigate the nanites will reappear as a medical scanner in "Relics".

The power cord of Wesley's unique microscope can be seen in this shot.

The shape of the red and black atoms in Wesley's molecular model in "Evolution" is called cuboctahedron. What remains after the Kelvans have reduced the Enterprise crew members to their base minerals in TOS: "By Any Other Name" are also cuboctahedrons.

A blue transparent PADD is seen on Wesley's desk. After orange and green transparent PADDs are known since season 2, this is the first appearance of a blue one. A different PADD of this type appears a few episodes later in "The Bonding".

Animations of moving, feeding and dividing nanites.

The nanites themselves were simple physical models by Rick Sternbach that were filmed. Presumably the motion of them turning was on film, whereas the side-to-side and up-and-down motion was animated in post production.

We can recognize more details of the circuitry in HD.

The typo "polarimetery" was corrected to "polarimetry".

The computer access room reappears in "The Bonding". After that, the set is redressed as the Utopia Planitia drafting room 5 one episode later in "Booby Trap".

The metallic looking grid on the walls of the computer access room appears in countless episodes, among them "Encounter at Farpoint", "Justice", "Too Short a Season" and "Datalore".

The computer access room is a redress of the versatile set last seen as the bridge of the Sheliak ship in "The Ensigns of Command" and before that as the bridge of the USS Hathaway in "Peak Performance".

The central console previously appeared in the tactical lab in "The Emissary".

Note that the micro-circuits from the graphics in the observation lounge appear as macroscopic versions in the computer core set.

The transparent blocks with green and blue circuitry were usually seen in Data's quarters and sickbay in the first and second season. As mentioned before, the red version of this block appeared in the medical lab earlier in the episode.

The beige/brown console on Stubbs's desk is also usually found in sickbay. It was part of the birthing chair in "The Child" and appeared in the geological lab in "Pen Pals".

Finally, the large black PADD Stubbs uses was often seen in sickbay in the first season.

The black sculpture resembling a woman's face is "Portrait of a Woman" by Klara Sever. It appears again after it was last seen in Tasha's quarters in "The Naked Now".

The aquarium in Stubbs's quarters was seen in Picard's quarters in the first and second season and in Wesley's quarters in "The Dauphin". After one final appearance in Troi's quarters in "The Survivors", it will be gone forever.

Stubbs apparently keeps the same stand-by console in his quarters as Wesley does in the sickbay lab.

The very same geode as in his quarters will appear in the teacher's office in "The Offspring".

Two bulky new Starfleet consoles with lots of LCARS buttons appear for the first time. Both will reappear in later TNG episodes.
