Here are all the callbacks buddie in 817 had to previous scenes I have found so far.
First off, obviously the grocery store fight in 306.
The scene also calls back to the fight before Shannon leaves in 315. The way it was filmed calls back to the breakup with Ana in 503.
It also calls back to the other 2 fights Buck and Eddie had, gym scene in 201, and the 809 one, because Eddie in black and the angles.
Color-wise, Buck's orange is similar to the one Shannon is wearing when she comes back in 207 ("what did you need that I didn't give you" "you") and Shannon and Eddie are in orange and black in 213.
Buck himself is wearing a similar shade of orange when he starts the lawsuit in 304, when he stops the car that fixes the lawsuit in 306, when he finds out about Daniel in 404, when he talks to Chris in 701. He's in a brighter version of it when he tells Maddie and Chim about therapy in 403.
There's the actual dialogue of Eddie calling back to his breakdown. That's the description of what happened to Eddie in 513.
Waking up in the middle of the night, to that news. Sitting alone in the dark. Trying to keep it together so I don't scare the crap
out of my kid.
Eddie walking in has similar visual cues to Eddie walking in after his therapy session in 514, from different angles.
The kitchen of it all calls back to Buck asking about Kim in 709, Buck finding out about Texas in 808, the talk in 612 if we decide to push it a little lol, granted the kitchen was a lot colder in 817 that we've ever seen it before.
Buck finding the note, obviously calls back to Shannon leaving. (Couch theory, you will forever be famous).
Buck is in that forest green we nicknamed the breakup green (even though the green is mostly about Buck being misguided in his own feelings, this is more about Buck jumping to conclusions, meta on the green here, please see the full picture of the use of green with Buck because it's fascinating), so call back that feeling.
I'm gonna treat Buck's shirt as both grey and blue because it looks bluer in some bits of the scene and greyer in others, just go with it for the sake of this exercise.
Most importantly, this scene calls back to the post-tsunami talk.
Inverted colors, but the same feeling, Eddie is using Chris to snap Buck out of it. This is a mirror if we count Buck's shirt as blue.
But if we count his shirt as grey, this is the mirror, 612. Both moments where Eddie is offering Buck something Buck doesn't know how to ask for.
The Chris of it all also calls back to 301, when Eddie storms into the loft to leave Chris with him. Eddie already being in the house also calls back to this.
If we count Buck's shirt as grey, we are calling back to the moments Buck is casually parenting Chris, like in 408 when Chris runs to the loft and when they are making the cookies in 613.
The scene as a whole calls back to after the earthquake, this one more if we count the shirt as blue, after the tsunami, after the shooting, but inverted, since Eddie is the one watching Chris with Buck this time.
The whole thing also calls back to 408 with Eddie coming home from the date with Ana (construction on sunset, baby), color-wise too since Eddie is that rust type color in both scenes.
Buck teasing Eddie about ordering pizza made me think of 707 after Buck burns the lasagna and the "20 Buck's for pizza" in 303, but that's a me thing.
Buck offering to cook in an ambiguous blueish-grey shirt calls back to Buck making them dinner in 601. (Couch theory conversation, anyone?)
Buck walking in visually calls back to the fight in 809. Eddie is leaning against the wall Buck wanted to tear down.
The Pepa of it all calls back to 204, with Buck watching Eddie and Chris and the actual conversation about "our Eddie". The conversation then evolves to something that reminds me of the conversation buddie had in 612. Eddie matches the couch.
Buck watching Eddie and Chris visually calls back to quite a few scenes. The facetime call with Chris and the Texas talk in 808 and Buck settling in in 811.
It also calls back to Eddie watching Buck and Chris on the couch in 612 and 615, and Eddie moving around them as they play in 403.
Now for the ones I'm less confident on, it's the wrong shades, but Chris leaving is Buck is in blue and Eddie is red.
And the groceries of it all made me think about 604 when Chris is helping Eddie with the groceries and they get the call that Chris has been lying about the science club. Mostly because Chris is holding the same brand of cereal that Buck is putting away.
I think this is all, I will come back if my brain gives me more.
A new commission for the lovely @evil-rainbow-sunshine (ofc about Starscream and the "I can't express my feelings for Optimus"TM). I already want to do something with Transformers+ Flowers and this was a very chance! I totally LOVE to work on this piece.
The choice for flowers were on Chrysanthemum a flower globally know for positive meaning and among them also "Optimism".
But, Fun fact: in Italy (and other EU country) White Crhysanthemum are associated with the dead (bc is a November flower) and I love casual double meaning. (Did you say "angst"? Say it double).
