The third sign that we see focused on in the episode is a No Running sign that Yuuji passes that says "Do Not Rush. It Is Dangerous." Yuuji, of course, runs past it on his way toward the escalators that lead (for him) to Gojo and (for the viewer) to Choso.

Once he does get to the bottom of the escalators, Yuuji is attacked by Choso immediately and Choso's opening move (Convergence), once Yuuji moves his arms up and away from his face, slices up through the subway cieling and the road above to cut the Pedestrian Do Not Cross sign that we saw at the beginning of the episode in half.

We also get out first big Left Arrow, placed immediately in the foreground of the shot and pointing toward the aforementioned sign that's been cut in half (this will be important later), but in a another view, it also points away from station itself. Again, go left to avoid danger.

Our next Left Arrow is on the ceiling between Yuuji, indicating that he should go away from Choso. Interestingly enough, it also points toward the bathrooms that Yuuji will go into later once his fight with Choso in the hallway becomes too dangerous.

That same arrow falls to the floor between them once Choso gets mad after Yuuji tells him about Eso and Kechizu crying, this time pointing directly away from Choso.

Another Left Arrow, this time in a more urgent red. We see this once Yuuji realizes that he's in serious danger, that he'll loose if he continues to fight Choso in the hallway. It's also pointing away from the bathrooms and toward the escalators from Yuuji's point of view beside the bathrooms, indicating that he needs to leave the area entirely.

The previous arrow pointing toward the bathrooms as a safe option has been destroyed and Yuuji has taken some serious damage by the time he moves toward them. The bathrooms are no longer safe. Yuuji needs to leave.

This is followed up by the only Right Arrows that we see focused on in the epsiode, but unlike the Left Arrows, they aren't used to convey how to get away from danger, but rather what is dangerous. Not only do these arrows all point toward Choso outside of the shot, they also have each of his techniques displayed below them.

Once the bathroom fight is over and Yuuji is on death's door, we get a zoomed out shot of his body framed by (two) people cut in half. This sign is shown right before Sukuna makes his only appearance in the episode, where we hear the sound of electricity flickering.

We heard this exact sound earlier from the Left Arrow telling Yuuji to get away from Choso at the beginning of the fight, but I like to interpret it as an audio indicator of Yuuji's life and/or control of Sukuna flickering in and out, becoming weaker.

Side Note: In the previous shot of Yuuji that we get before this one, we see a blade of light cutting Yuuji in half, the same way Convergence cut the Pedestrian Do Not Cross sign in half earlier in the episode. This will come into play later in the post, but keep it in mind.

The next time we see these bisected bathroom signs is when Mimiko and Nanako approach Yuuji to awaken Sukuna. Two people framing Yuuji/Sukuna that have been cut, while those same signs are whole in the hallway to the left. Go left to avoid danger applies to the girls here as well.

Our next important set of signs are actually the same sign, a large green arrow in the foreground that points away from where Yuuji's body is. While Choso stumbles away from it (away from Yuuji/Sukuna) the girls walk toward it.

This is also the first Left Arrow that we see point toward Choso, unlike the one pointing away from him at the beginning of his and Yuuji's fight. Choso, at this moment and onward, is no longer a source of danger to Yuuji or to us, the viewer.

And finally, the final shot of the entire episode, our old friend, the Pedestrian Do Not Cross sign. Yuuji has lost to Choso, the girls have found him to awaken Sukuna, and we get a focus shot of the Pedestrian that previously represented Yuuji cut in half and covered in blood.

I mentioned earlier that we get another shot of Yuuji cut in half by a ray of light in the bathroom.

Here is that shot, and the way that I interpret it is as a reminder that Yuuji shares his body. Yuuji's control of his body has been cut off in the same way that the Pedestrian representing Yuuji has had part of it cut away. What's left is the part that Yuuji can't control, the Pedestrian covered in blood.
