"Water has 2 oxygens in it so how could you drown? ...Yes I know that's wrong, that was the joke"

Unlike his friend the stoic Niall, Robert loves to talk to people and make jokes, though on the other hand he has a bad habit of accidently coming off as rude due to being introverted and so tends to become extremely awkward when his social battery is low, and on top of that, like Magnolia, while it is hard make him angry, once he is he (figurately) blows up.
