I can't help but worry about you sometimes, Helios... [Not because Robert thinks he's incapable, but because he just... worries. And Helios is his friend and not-boyfriend and he cares about his well-being on principle.]

You know how much I... I care for you. [That momentary hitch probably betrays the lingering feelings there, but Robert doesn't say anything aloud, just briefly grasps Helios' hand if the headmaster will let him.] So I do not want any harm to come to you.
