I personally didn't give much thought to the romances in Animorphs. I mean, I loved Jake/Cassie to death, sure. And Tobias/Rachel was cute. But I never really went passed the books. I didn't search fanfictions or fanart like I normally do with other fandoms I follow. So, just a few days ago, I decided to just go searching for fanart and music videos and junk and I was surprised to find videos for Tobias/Cassie and fanart for Marco/Rachel. I didn't think about the couples so much so I never really thought about how the characters would turn out if they weren't with who they were. I mean, imagine if Jake and Rachel never really cared about the fact they were cousins?
After all, Jake has explained Rachel to be his beautiful cousin in almost every narrative of his but the only reason he never saw her that way was just that - because they were related. And in book # 32, where Rachel was split in two in the Starfish morph and had separated in to two. The "nice" Rachel said "Jake was there. He's my cousin. He's cute. Kind of big. I mean, if we weren't cousins . . ."
In MM4, Rachel thought about dating Marco (correct me if I'm wrong) and well, some people support Ax/Cassie because she helped comfort him when his heart was broken by the female Andalite (whose name I can't remember right now XD) And Tobias/Cassie is supported because I think a lot of people see how similar the two are, just like how similar Rachel and Jake can be?
So yeah, what do you think? Do you think about different couples? And how do you think the characters would have turned out if they had someone else to lean on instead of the person they did have?
