"Just marry me already..." - Reiner Braun
I find this interesting because during the Castle Utgard chapter, Reiner came upon Ymir scavenging through the castles food stocks and Ymir, surprised, asked Reiner if he had the kinky habit of sneaking up on girls. Reiner responded something like "Eh? I thought I didn't look like the type who went for girls" and Ymir answered in the mutual (Not going for guys). Now here's the even stranger part, if Reiner was gay then you'd figured it would be for Bertholt whom he's always seen in the company of, right? However after revealing himself to be the Armoured Titan and escaping with kidnapped Eren, in the Forest of Giant Trees Reiner told Bertholt "When we get Annie back and return to home town, you gotta confess your feelings man" Bertholt blushed and said he didn't know what Reiner was talking about and Reiner responded that it was obvious with the way Bertholt was always staring at her (Annie). So if Reiner accepts that Bertholt has a crush on Annie, and Ymir has a crush on Historia (Christa) then where does that leave Reiner's romantic intentions?
