Picture #2: this could be the Dauntless coming across the wreckage of the destroyed relay station. At least, it's a possible explanation for the shocked appareance of the crew. Alternatively, they could be coming across the Borg cube, but I doubt they would be so hot on the heels of the Protostar already.
Picture #3 (and the following) are intriguing. Was a copy of the Diviners holoprogram saved? If so, why do they access it only now?
Picture #9 and #10: this may be the "protogies" coming across the "living construct", as they look shocked to a space beneath the bridge, while Jankom apparently thinks he can destroy it with a phaser. I'm guessing it won't be that easy.
Picture #16: Jankom Pog already feels at home on the cube, maybe ready for some "concussive engineering"?
Picture #20: Aw. Guess Zero succeeds in saving the day.
I wonder why Gwyn is singled out in the title card for the episode (her and only her surrounded by Borg drones) while Zero is apparently the key character this episode.
This looks like it will be a thrilling episode. Looking forward to it.
