Now she and the League must deal with an attack from garishly dressed superpowered teenagers. One of whom claims… no, that’s ridiculous. Even if she is wearing Wally’s old Kid Flash costume. Sorry, Hermione, but everything’s about to start going wibbly wobbly!
“Grife, Mum, you’re embarrassing me!”
Notes:
Hermione first (knowingly) encountered time travellers way back in Lantern Granger: Her First Year - First Chrononautics. Which also is when a rather important person in Hermione’s life makes their first appearance in the series, both in person and as statuary.
