I think it's good that there is a bit of romance and they seem like a great couple, changing the topic slightly.. did any of you think Capcom made Sherry seem, weak? I mean you would've thought after becoming an agent and having traces of G in her, she wouldn't need to rely on Jake to save her a lot? Unless Capcom is trying to build her character up. xD
Actually yes, she did seem extremely fragile and incompetent, like a foil character for the awesome and badass Jake.
In Ch 1, when they first encounter a Jake swing-able pole, he swings on it and asks Sherry to follow him like it's no big deal. She explains something like shes "not a circus performer," essentially degrading herself, and making them have to find another way for poor little Sherry.
When they first start Ch 3 and they are unarmed, they say the exact opposite about their fighting capabilities. Sherry says "I'm not even going to attempt to fight until i find a gun," where Jake embraces confidence in his abilities saying something roughly like "I don't need a weapon to take down you assholes."
It doesn't stop at physical prowess either, Jake seems to crush her mental capabilities as well. When you encounter the statue in Ch 3 that needs 10 ID tokens to open the door, it has Chinese writing on it. When you read it as Jake, he translates it. When you read it as Sherry, she says "Jake could probably read this."
Then, when your getting the ID tokens themselves, to get one of them you have to play on a piano. If you play it as Jake, he plays a complicated classical piece with great skill. When you play it as Sherry, she slopily plays the tune to "twinkle twinkle little star" or "the alphabet."
Both the piano and the Chinese writing imply that Jake is not only more cultured than Sherry, but also an extremely fast learner. Pretty much the only thing Sherry has over Jake is her healing, which he frequently compliments (i.e. "supergirl"), and her unwavering idealism/innocence, which he actually picks up himself towards the end of the game (as seen with the middle eastern Napad scene). I always notice these details.
