Not exactly a life-or-death situation here, it's just a YouTube comment I'm in the process of typing in a discussion on movies, the MCU, and the MCU's version of Spider-Man. Sometimes, I write a sentence and immediately question the syntax, but this time I have four distinct questions about one silly sentence, and I figure I may as well ask so I'll have that information in the future.
It's the same reason I don't really care for any of the other "spiders": A huge reason for Spidey's success was that he was unique, and he was a loner; there was no one else like him in comics.
The primary question that has me going as far as to ask for clarification: Is this the proper usage of capitalization after a colon? But then, I immediately have other questions.
Does the colon belong in or out of the quotation mark? If it matters, this is a case of quotes being used to denote what people are unofficially calling other characters with the same power set, not a direct quote from someone.
Is double-spacing after a colon still correct? I know that it's no longer encouraged to double-space after every sentence as I was taught back in typing class (though I still do it out of habit and preference), and I could swear we were taught the same for colons, but I don't know if it's the current, proper syntax.
Should there be a comma after "unique"? <-- (And does that question mark belong in or out of the quotation marks?)
Is the usage of a semicolon toward the end of the sentence correct? I think I've started to overuse semicolons the way my English professor once told me I overuse parenthetical phrases, but is it grammatically correct? I'm especially concerned considering everything else going on in the sentence, but it is important to me (for...whatever reason) to keep closely-related thoughts connected in this sort of way. But is too much?
