Spoilers for Arcane S2 Act III
If I had a nickel every time 2 characters start on bad terms only for one of them to save the other in the very same episode which kicks of their friendship which is essential to their arcs and makes the one saved a better person and helps him achieve everything he has ever dreamed of and more while the other slowly loses himself, disregarding his own morals for the greater good while working in the shadows towards their shared goal but gets tunnel vision and forgets himself (which leads to the destruction of everything he worked for) and they are referred to as/called the two sides of the same coin and at the end they hold one another as they/one of them die (and btw one of the characters is in relationship with this badass woman he doesn't deserve but still choses to spend his last moments in the presence and only thinking about the sassy twink that has been there for him for years) and they don't kiss, it isn't outright stated that they love each other romantically but there is love, it is beyond friendshp, brotherhood or partnersip, they are soulmates...
