By the way, in two weeks it's Jearmin week on tumblr :

And Jean already left his faith in humanity on Connie's shirt, so he may leave his heterosexuality on Mikasa's scarf...
In the end, shipping is more of a funny thing to do when you are bored or tired because you always end up with funny situations/results.
Things like Mikasha fanarts ends up to be really cute most of the time, it's like ice cream you have the cold side and the sweet side.
AND NOW TO YMORIA or HIMIR, do we even know how they consider gay/bi/lesbian/trans in the walls, because Ymir once said that they should get married after the operation in Trost... And well, I'm pretty damn curious on how a society living in a closed space with a victorian-something way of life react to this kind of social problems (like marriage, we don't even know how this works in there, the closest person to get married there, suddenly started to do some yoga against a tree so we don't even know how it looks/is organized).

Edit to do some shipping once and for all :
Jean & Hitch (and I really would love this one)
Science & Zoe
Sasha X Potato Springer or Mikasha or Sa/sha/muel (yup we forget a bit too much this poor dude)
Eren X Mikasa or Eren X chill pills
Armin can go with whoever he wants, it will always be a beautiful couple with him in it.

(and I'm serious, all the fanarts shipping Armin are always funny or cute so I approve all of them, here you go little buddy the key to a harem with everyone in it)
Petra X Yoga X Rivaille/Levi
Marco still needs to find his other half...
Auruo X a haircut
Hismir (Ymoria)
if not possible for Ymir : It's okay if she gets one of the teen titans...
Bertie : just go with one of the teen titans... OR WHY NOT BOTH ?
well in fact I'm okay with almost all the ships...
The only one I don't want is JeanKasa Kirschkermann.
