There had been times when it had been offered to her, her own well being over Gamora's but she had never been able to take it, needing her sister to be safe just as much as she was also. It was a small relief to hear that at least one person would not harm them in this place - she thought the strange men she and Gamora were staying with could probably be counted as well.

For now though they could focus on the books together, they could see what there was there and maybe if she was very lucky she'd find just a little more of that feeling again.
