Elros drops the loaf of bread that he had just picked up when he whirls around, ducking his head automatically. There is a faint relief when he sees Maglor, because even when the shorter of the two sons of Fëanor is being scary (and he can definitely be) Elros still feels safer with him, just because their connection is stronger. And even while right now he doesn't think that there is an issue of safety here, only one of having gotten themselves into more trouble than they thought they would, it is still better for Maglor to have found him.

He doesn't say a word though, only stands there. Not like there is a good place to run now, and it will probably make the older elf even more angry.
