Mizuki watched each action he made with the utmost caution completely untrusting as he looked at her hidden beneath the bed having thought she'd picked out a good hiding place and wondering how he'd found her in the first place. She crawled out backwards from under the bed to get some distance between them, she was cautious and clever two traits that made her a very difficult experiment and now that she was older it would only be more difficult especially after having escaped that place. Her lack of speech was due to the decreased time of interaction that she'd had over the years, having had no real need to it was almost as though she'd forgotten most her words.
