(1)
Acrostic poems are the hint here, I won't be backwards in warning you. ^_~
(2)
This refers to a specific episode in classic who from the Tom Baker era.
Hint two: foils are a light sword used for fencing practice. The Doctor prefers the real thing.
(3)
For non Harry Potter fans, the original (much better) sphinx riddle I took off went:
First think of the person who lives in disguise,
Who deals in secrets and tells naught but lies (answer: spy)
Next, tell me what's always the last thing to mend,
The middle of middle and end of the end? (answer: d)
And finally give me the sound often heard
During the search of a hard-to-find word. (answer: er)
Now string them together, and answer me this,
What creature would you be unwilling to kiss? (overall riddle answer: spider)
Hint two: this is an older riddle, and so some of the numbers at the end (such as 10), may have been superceded by canon.
(4)
Refers to specific companion from the classic Doctor Who era.
Hint two: not all characteristics described were held by this character at the same time
(5)
Almost entirely wordplay. 'The most important word in the English language' refers to a line Tegan from the classic series once delivered while in a panic about an index file she couldn't access.
(6)
Why are there two capitalised letters at the beginning of the riddle instead of one?
(7)
More word or letter play. Every second of my riddles seems to have this...
Hint two: the why of the first companion from the new series who died yet lived to fight.
