NEVER. MET. AT. ALL.

Okay, I looked up this ship on Bulbapedia. I was really shocked to find out that they have a lot in common. 

-They both are Gym Leaders.

-They both have two siblings the same age as them.

-Both are romantics and "get themselves involved with Pokemon who fall in love".

-Both enjoy fishing.

-Both have a special lure.

So, I think that they would be an okay couple. However, I think that Cilan might aggravate Misty so much, that she might need another hammer.

Rating: 8/10.
