Kurt glanced sidelong at Loki but decided a non-reaction was the best course of action. Although when it came to 'anyone', he half-muttered, "Some more than others." He could name more than a few.
He had already decided he wasn't ever going to trust Loki wholly or at least he could always assume that the old god would have an interest at hand other than Kurt's well-being. "I'm very acrobatic. It's not really necessary - it's just something I can do and enjoy doing." Glowing yellow eyes turned to Loki properly as he thought on the advice but he wouldn't make his decision just yet. "Maybe I'll hide in the kitchen then. At least I can eat beforehand."
As for the professor, Kurt smile as his tail swished back and forth. Apparently Loki had found a topic that didn't make Kurt feel self-conscious. "Charles Xavier runs a school for mutants like myself. His and our ultimate goal is to live in peace and acceptance with non-mutants and he helps us come to terms with our powers and train in their use."
