Yes, I went to see them again.
This time, I followed Jayce’s storyline. I really loved the little details this actor added to Jayce’s portrayal;

1. Viktor coughs violently while conducting experiments.
   Jayce: "Are you okay?" (pats him)

Cassandra praises Jayce ，while what jayce doing is whisper to Viktor.
When Cassandra speaks to Viktor about the forbidden romance between the Undercity and the upper city resulting in a child with magical powers, Jayce keeps his eyes on Viktor the whole time.
Later, Viktor talks about building a small boat as a child because he couldn't keep up with the others; he sits on the floor and cries, and Jayce kneels beside him to comfort him.

When Viktor dies, Jayce holds him the entire time.
Afterward, he keeps holding onto Viktor's gear.

When Viktor comes back to life:
Viktor: "Jayce..."
Jayce: "Viktor..." (he hesitates for a moment, wondering if it's real) ...then he immediately rushes over to hug Viktor, returns the gear to him, and wraps a blanket around him.

5. Viktor: "you promised me you would destroy Hextech."
   Jayce: "Do you think this is easy for me? Am I supposed to bear the weight of Hextech and its consequences all alone? Am I supposed to remain unmoved even as my best friend dies in my arms?" (his voice clearly thick with tears)
   Viktor: "Jayce, you know I was supposed to die; this can't be undone—just like how you've killed people before..."
   Jayce: "It's not like that, it's not like that..."

6. I almost lost track of Jayce here... because after Viktor left, Jayce sang for about 30 seconds—something about how maybe he shouldn't have crossed that line—and then... he shouted "Viktor!" twice and ran out.
   (I once saw a headcanon that Jayce would shout Viktor's name all over the Undercity after Viktor left, asking everyone if they'd seen him; for me, that's canon now.)
   (I can't blame him! If I had nearly lost my partner, only for my partner—freshly recovered from a severe illness—to say he wanted a divorce and then walk out wrapped in a blanket without knowing where he was going... I’d react the same way.)

7. Jayce finds him.,
   Here is what Jayce said: You have always strived for perfection, but your illness and your leg—these are what made you who you were in the beginning. A perfect you. That is the version of you I cherish.

…I literally screamed when he said, "your best partner."

Ugh, my Jayvik brainrot has flared up again after watching the Arcane musical.

So I have to talk to you about my favorite part about Jayvik (the part that's different from the TV series).

TW: suicide, violence, spoilers

Viktor attempts to end his life with a tie in musical, but Jayce arrives and persuades him to stop. Jayce kneels and ties Viktor's tie, saying many things.

Then they are all in the council, where Cassandra tells them a story: Once upon a time, there was a couple, a nobleman from the upper city and a commoner from the lower city. They shouldn't have fallen in love, but they united in the water and gave birth to a magical child. However, because the child was born of light and darkness, it was destined not to exist in this world. The parents tried to raise the child with tenderness, but to no avail. Finally, they could only ask the gods to take the child back to its birthplace and kill it. (It's said that in some shows Viktor tells Jayce that Cassandra is talking about Hex.)

Afterwards, Viktor says it's a lie, a fabricated story. Jayce tells Cassandra that this is his partner, Viktor, who comes from the undercity, and he can give them Hextech, with the only condition being autonomy for the undercity.Cassandra holds a vote, and everyone agrees.

They are going to declare the undercity is autonomous now.Jayce was there for the announcement of self-government, but before that, Viktor told Jayce that when he was a child, he built a small boat because other kids could go to the secret base, but he couldn't because of his leg problems. He used to think the boat could take him anywhere—the secret base, the upper town—what a ridiculous thought!Jayce said he promised Viktor that even if the boat couldn't go anywhere, at least he wouldn't be alone by the river bank this time. They would think of a solution besides the Shimmer.

Then Jayce, Viktor, and Cassandra announced self-government. Jayce said, "You may not know me or my partner Viktor, but whether you agree or not, we are announcing self-government here today."Then came Jinx's bomb.

This made me wonder what Jayce's original plan was in the musical. Did he originally intend to quit his job to be with Viktor?
