Part of Theo's attention was locked on Charlie's wand, tracing the movements and tense in case it came his way, but it was all instinctive; the very fact that he was listening to Charlie at all spoke to the trust that was there.
He was touched at Charlie's offer but torn between being a bother by having to be levitated or being a bother by taking forever to walk up the stairs. He closed his eyes and took a deep breath before shaking his head. "It's okay, I can handle the stairs." he assured, pushing the pain from his feet to the back of his mind and shutting it off, compartmentalising in a way that was too easy for him to not have done it before. "I'll follow you." he offered, not wanting to slow Charlie down. He was still groggy from sleep and nothing seemed real. He was still twitchy with tension and his body flinched involuntarily from time to time.
