Someone has already pointed out the splatter on Buck's shirt as foreshadowing. But not only that, but Buck also changes to the parenting maroon, aka the color he is wearing when he steps up with Chris, both during the tsunami and 414. (Breakdown of the blue and red and parenting here)

So, in the same way the shooting makes Buck a parent on purpose, he makes the choice to be there for Chris without anyone asking him to, this could also lead to Buck making the choice to be the one to adopt Theo if he goes into the system.

Theo's sneakers and the balloon make him the red for Buck and Eddie's blue in a similar way Chris' glasses and that borrowed hoodie do for Chris in 303.

In the same parenting colors, the show uses blue and red for parenthood. Hen and Karen decide they want another kid in a blue and red playground. Same as the discussion about Buck's lack of involvement with Theo because he would get attached.

Fitting into the Buckley Diaz family color wheel theory, part of the blue and yellow of it all, explained here, Theo has blue, red, and yellow on him for 2 out of 3 outfits.

The 3rd being Theo fully becoming the red element to Buck's blue, similar to Eddie rushing to Chris in 303.

The conversation Buck and Eddie have in the playground parallels the sentiment of one of the fights Eddie has with Shannon in 315. The feeling of not knowing your kid, your kid not knowing you, the helplessness of not knowing what's best, also, they imply that Theo is the same age Chris was when Eddie came back and became a single father. That conversation also parallels 210 and the fountain scene, where Eddie explains the way he was running in a similar fashion Buck ran from knowing Theo.

Visually, the crash is a mirror of Shannon's death.

I don't know why, but I'm stuck on this.

Lately, there's been a focus on buddie inside the ambulance, and it keeps bringing me back to 201.

Everything about buddie goes back to the choice to walk into that ambulance together and taking care of each other ever since.

Obviously, there's the blue and yellow of the bridge. Both of them are surrounded by their own colors, both of them wearing both blue and yellow.

But this also attaches this life-changing moment for Buck to the event that defines Eddie, since Shannon's death is blue and yellow. Which, paired with the way we see Eddie frustrated about Theo's emergency placement, attaches Eddie to this, too. Eddie becoming a single parent changed their dynamic, it made them stronger, the expectation would be that Buck ending up in the same situation will have the same effect.

Also, Shannon dies in 217, leaving Eddie to be a single father, 917 leaving Buck to be a single father. 218 with Buck almost dying, 918 with Eddie in danger, the parallels are paralleling.

Like I said a couple weeks ago, it's all shaping up to be a repeat of what makes them meet, but this time they have all the tools to help each other already. Buck is living through the concept of Eddie Begins, but unlike Eddie, Buck has someone in his corner. So it seems like we are about to see a "what happens if they do it all again, but without the distractions that make them stop looking at each other". Because Eddie stepping up with Buck for this, while both of them are single, there's only so much you can still rationalize before you make them crash together. So, in a similar vein to how 704 is "what if Eddie had grabbed Buck and kissed him in 201" this kinda feels like a "what would happen if both of them were single and weirder about each other and queer when they stumbled into coparenting." Everything about this can lead to the realization that they are family and they already have the partnership they crave.

Also, because, well, Buck, Eddie, their teenager, and their toddler is too much. The plausible deniability has left the chat.

But what I'm trying to say is that this episode feels like Tim finally getting back as many triggers Fox censored as possible. So I'm intrigued. We'll see how this unfolds in s10.
