Perhaps it would help (help you stop arguing with Marc) if you just consider it a 
spiritual connection and stop dwelling on the biology.

Perhaps they do. I see no evidence that they don't. Are we shown any means by which
inhumi get to Blue?

Aren't gardens supposed to provide a food source? Why would it have a liana?
And if it did previously have one on that tree, perhaps it is gone because it 
turned into Quetzal ;- ).
