A heathen? How else was he supposed to eat - especially if he was under some sort of house arrest, as he was? Of course, he didn't have the moment to respond and with how he'd embarrassed himself the last time he saw the older vampire, it was probably for the best at this point. Again, he was wondering how he had gotten so mouthy, especially around people that could end him without a second thought. Was there some sort of personality transfer between sire and child? Maybe... He could ask about it later.
Rhys only hesitated for a moment before he moved to follow Amadeus, silent for the moment. When he'd first come here, the passages in the haven had had a weird way of resetting themselves, putting him back to the room he had just left, but that was before he'd been embraced. Henry had taken whatever it was doing that down but had never had a chance to put it back up. Or that's what Rhys thought. He didn't know how it worked, or didn't, he just knew it didn't happen anymore. A point that was brought to his thoughts as they made it to the kitchen without a problem.
Again, he was silent as the other man poured his bag of blood into a cup, probably the only one they even had for all he knew, only flinching slightly when that bladed ring once again made itself known. Memories of having his own blood taken by it made him want to move back, just in case, but it wasn't for him this time. Part of him wanted to get a cloth and cover it up but he held still, listening instead of doing. Henry had said similar things the first time the baby Tremere had fed but it had been focused on the blood of kine, not other vampires. Was it alright, really?
Another hesitation before long fingers reached out, taking the mug from him. It wasn't like he was trying to kill him, at least not right now. "Th-thank you." It was quiet before green eyes looked down, teeth chewing on the corner of his lips before he went to take a sip, shuddering a bit at the taste. It wasn't bad, it just wasn't what he was used to. Or the temperature he was used to. "I have to drink a lot when I do magic?"
