Gladio likes to hold Ignis's hand, and vice versa.
+They hold each other's hand walking around the castle and people (especially Clarus) think it's adorable
++Ignis likes to swing their arms a bit when they go out and Gladio holds his hand
+++++Pictures of them holding hands has appeared in the paper- Iris likes to cut them out to put on the fridge or show Gladio
+++One time, Gentiana came across Gladio and Ignis holding hands while watching Noctis and Prompto train. Ignis was asleep at the time, but Gentiana gave Gladio the protective bff speech and blessed their union (despite the fact that they were waiting a few years for marriage but sure Gentiana, you can be the maid of honor)
