When Thranduil (and the whole Mirkwood) needs a break, this will happen:
(Somewhere in Rivendell)
Thranduil: Legolas, you are going to stay with Lord Elrond for a few days(months). Be a good boy.
Elrond:W-What??! (Nevermind... I will have Lindir take care of all this...)
Lindir: (oh...oh no...)
This drawing is the sequel of my last drawing, which can be found here: [link]
Since the age of Legolas is not mentioned in Tolkein's book, I just assume that he has around the same age as Arwen. (So they can play together)
I'm also assuming Thranduil and lord Elrond are good friends.-_- So they can send their kids to each other's place for a super long '/sleepover/'.
And Lindir is secretly upset because he knows his lord Elrond, as always, will have him take care of the kids.
(That's why I drew him with puppy eyes at the corner)
