"Neelix still composed letters to Alixia, under file index 291 in his personal database" - It didn't sound to me like he was composing a letter to her, he was just pulling up her picture out of sadness/loneliness/regret. – The preceding unsigned comment was added by 184.108.40.206 (talk).
If Alixia is Neelix's full sister, then her species listing should include 1/8 Mylean like his. Otherwise, she should be listed as his half-sister. One or the other must be true. In the absence of any canonical information indicating she is only a half-sister, then officially she would be a normal sister and thus 7/8 Talaxian & 1/8 Mylean due to having the same parents as Neelix. --220.127.116.11 14:00, August 15, 2016 (UTC)
