I love the concept that Viktor ends up with Jayce’s last name through some originally non-romantic means so much that I have multiple versions.
Jayce accidentally gives Viktor his last name by being so insistent on putting Viktor’s name first in every circumstance. When he’s listing their names on anything he puts them down as “Viktor and Jayce Talis”. When he introduces them to people he says “Nice to meet you, this is Viktor and I’m Jayce Talis” with a pause before Talis because he always forgets that he should say his house name too. Viktor slowly starts to notice that they’re referred to in the tabloids as “the Talises” and that higher ups at the academy will introduce him to investors as “Viktor Talis” without Jayce even being there.
When they first start working together, they put their initials next to things in their shared notes to mark when they have questions or agree with something the other wrote, or to differentiate when someone is dictating while the other talks. In an effort to not have it confused with a variable, Viktor initials VT (VikTor) as a bit of a joke to look similar to Jayce’s JT. However, one day when Heimerdinger is looking over their notes, he marks out a question in the margin for Viktor with “Viktor Talis” written out next to it in full. Viktor and Jayce debate for a moment after he leaves if it was supposed to mean it was for both of them, but the contents of the question makes it entirely clear that Heimerdinger things VT stands for Viktor Talis and has accepted that Viktor has adopted Jayce’s last name with no questions.
At the beginning of Hextech, as they are trying to get investors, Viktor regularly gets identified as being from the undercity and harassed for it by wealthy Pilties when he tells them his name is “just Viktor” when asked what house he is from. So one day Jayce suggests just telling investors that his last name is also Talis, thinking that people will assume they are brothers. Viktor gets flustered and tries to politely decline, but Jayce seems to confident that he lets it happen. It takes him weeks to figure out that Jayce doesn’t realize that everyone thinks they’ve gotten married or plan to. Viktor doesn’t have the heart to tell him and won’t let Mel break the illusion.
Jayce takes Viktor on a tour of the forge and when he gets done takes a hammer to jokingly knight him and dub him “officially part of house Talis” Jayce thinks nothing of it until the next time they meet someone new together when he almost spits out his drink hearing Viktor introduce himself as “Viktor Talis”
Some investor that they fucking hate can’t keep their names straight for some reason but always sees Jayce wearing his house sigil so he says “ah, Viktor Talis” every time he sees Jayce. They find it so fucking funny that even just saying “Viktor Talis” sends them into uncontrollable laughter.
Ximena refers to them exclusively as “my boys” to the point that most people who met her after Hextech was founded assume that she has two sons, Jayce Talis and Viktor Talis. She doesn’t feel the need to correct them as she does truly love them both as her children and is also quietly hoping one day Jayce will get his head out of his ass and ask Viktor out on a date.
