Maybe Hob carried (or still carries) a small torch for Dream. It's hard to make heads or tails of his feelings toward the Endless, at times, but Hob called Loki here because he did want to see him. Very much. And whenever Loki looks at him with his adoring gaze, it makes Hob feel something so fulfilling it's as though he might burst with happiness.

When Loki joins him, Hob sits up a bit more and offers a hand to accept the tea. If it's something similar to what Loki's mother used to make him, Hob wants to try it right away.

The idea that Loki should come back later has Hob shaking his head. "I didn't ask you to come here to make tea and leave." There's a bit of humor in his voice. "I wanted to see you. Please, stay."
