You guys remember that one scene in World Tour where Alejandro gave all his candy to Cody because he wanted to form an alliance with him? I feel like that would be their entire relationship. Alejandro letting Cody "borrow" his hoodies and jackets never to see them again. Alejandro making cakes or taking Cody out just for the fun of it. Alejandro just doing all these things to make Cody happy.
Or, alternatively, Alejandro gives Cody the Bridgette/Leshawna/Courtney treatment, joins forces with Heather to get him kicked off (Sierra voting Alejandro because he "stole" Cody from her, Cody voting Sierra because obviously), and Alejandro telling hellbent Sierra it was Heather's fault because something something jealousy.
Looking at things from a non competitive perspective,
Ship Rating: 7/10 (just because I prefer Malejandro and NoCo)
