Alex saw how confused Reine was, well he didn't blame him, he slept unconscious for two months stuck on thay bed, so ofcourse, there's a lot that he's yet to understand about their whole situation.
And right now, he didn't quite know how to explain to him when he looked so dead with his pale skin and torn lips as well as his Icy eyes, to others, he may even look a bit quite scary. But Alex knew way better, that he was only like this because he was sick and probably didn't have enough food as he barely ate when they fed him while he was unconscious. But soon, the three men he sent to bring food for Reine came back and took the food on the tray of their hands before he went and sat next to him.
He took a spoon as he filled it with rice and beans before he placed it on his mouth while saying
"Your highness, it has been a while since you had proper food, please have some, you'd feel better in an instant"
