Bee Wing quest question

[Bakorzero]

So, before I begin this quest I have several question :
lets say I have char A and char B in 1 account
1. If I do the quest with char A does char B can use the wing ?
2. Char A can ask the drop selection to bee queen, does char B can too ?
3. or char B must do the quest too ?
4. So bee wing drop selection is char based ?
5. Or we just wear it and ask the bee queen ?
