Hidden Details: Dinner Despair

Welcome to the eighty-eighth episode of the Hidden Details blog!

Have you found some obscure reference or detail in this comic? A JoJo reference? A sneaky little Loss? A callback to a previous comic? Let us know what you've found in the comments! Every detail that has been found will be added to the list below. Once everything has been found, this comic will officially be marked with "all details found".

Please only comment with ONE hidden detail or reference!

There ONE Loss, ONE Balthazar, and ONE JoJo reference. Bonus panels don't count.

1: There's some references in Sephiroth's speech, as pointed out by Zanreo. In the first panel, he says "everyone is here", which is Smash Ultimate's tagline, and later he says "everyone is dead", referencing the World of Light memes, but also this arc itself.
2: There's a nice E3 banner hanging behind the fighters in the first panel.
3: Everyone is indeed wearing bowties, Erin! And they also happen to be E3 colours!
4: Chef Squirtle is still wearing his little chef hat.
5: Link is indeed a leftie in this comic, Zach! When drawing Link I had already drawn a bunch of other characters when I realized this would be a nice detail, so I had to redraw a few of them to make Link's left-handedness stand out, hahaha.
6: Sephiroth has an absurdly long knife. Good catch John Hattan, I wasn't sure if it was obvious enough. It's indeed a reference to his sword in Final Fantasy VII and Smash.
7: Correct, Zach Strand! As part of his big reveal, Sephiroth has apparently flipped another banner over the previous one, replacing the E3 banner with One-Winged Angel lyrics.
8: Haha yeah, I initially drew those ゴゴゴ's as a joke but they kinda fitted, so I kept them, Marwan Abunura. Consider this another JoJo reference.
9: Sephiroth has indeed put a little Sephibutt drawing in Cloud's drink to announce his evil scheme, Cameron Devera.
10: Haha yeah, the loss was very obvious this week. It's indeed on the toilet door. Still, nicely found, Luke.
11: Marth's tiara drops from his head when he dies and can be seen on the table afterwards.
12: There is yet another Balthazar picture visible  in the final panel. If all those pictures are canon, every wall in that house has one, it seems. Good find, Dirtydan8991.
13: Kazuya brought some stuff, like his pink toothbrush. Dental hygiene is important. I'm sure you'll agree, Phloxiana.
14: And yes, there's a little Smash logo on the mailbox in front of the house, Trigger.

After one week, I'll reveal all the details that haven't been found. These ones are written in italic.
