Lady Dis and Dwalin. I ship em.

My Headcanon:

When Dis was little she had a huge crush on Dwalin. She would always call him “Ser Dwalin” because he was a like a knight to her, and she tell everyone that she’s gonna marry him and have a bunch of kids with him.  Dwalin is like “Aw how sweet” but she’s totally off limits because she’s a princess and his best friend’s younger sister.

Then after Smaug sacks Erebor they don’t see each other for awhile. Years pass and finally Dwalin meets Dis again and she has grown up to be a very beautiful dwarf woman.He always did love her but now for sure he’s in love with her. Not only for her beauty, but because she’s strong, independent, and she’s optimistic even in dreadful situations where her family and her people had to live on the road. She’s the light of his life. But sadly he can’t stay for long, he follows Thorin and everybody to Moria and after that he’s gone his separate way. He goes to Ered Luin where Thorin and his family is to finally settle there. He’s thinking maybe it’s time he should court Dis, since political marriage is not an issue anymore. He meets her again and she’s even more beautiful, but he notices something (her marriage bead or ring). It’s too late, she has already married and to twist his heart even further she is with child (Fili). He’s sad but happy for her as long as she is happy and she is. Her husband is very good to her and loves her dearly. She loves her husband but deep down she still loves Dwalin and wished he asked her sooner.
