I saw someone mention they headcanon Shane as a rainbow baby and that's all I've been thinking about all day and the more I think about it, the more I feel like it really could be canon or at least implied canon.
David mentioned in TLG that him and Yuna "could only have one child" and that they even considered adoption after having Shane which implies they had fertility issues.
Imagine a young Yuna and David being all excited about the prospect of starting a family together only to be met with difficulties getting pregnant after months, maybe even years, of trying. Imagine the absolute heartbreak when they do finally manage to get pregnant only for it to end in a miscarriage. Poor Yuna probably blamed herself and David was probably doing his best to be supportive and strong for his wife while she was at a mental and emotional low. Maybe they take a break from trying for a little while to heal emotionally. When their spirits are in a better place, they decide to start trying again and to their surprise and delight, they managed to get pregnant again. Yuna is overjoyed but also terrified of another miscarriage happening so she and David do everything in their power to keep her mind and body as calm and stress-free as possible throughout the pregnancy.
After 9 months, filled with hope and anxiety, their baby boy Shane came to them in the spring.
Him being their rainbow baby just adds a whole other layer to their love for him and I don't even care if it's not proper canon, I am now a rainbow baby Shane truther!
