Carol responds:

1) Mark Evans is a Muggle-born wizard distantly related to Harry
through a Squib ancestor and will be sorted into Gryffindor. (At least
I wasn't alone in being *sure* that the last name he shared with Lily
and Petunia was an important clue.) <blush!>

2) Lily's proficiency at Charms, suggested by Ollivander's description
of her first wand as "a nice wand for Charm work," led her to cast a
sort of super-Protego Charm on baby Harry that would be activated by
her self-sacrifice. As part of the charm, which may also have involved
a potion, she marked Harry's forehead with an eihwaz rune (symbolizing
protection) which reveals itself in the shape of Harry's scar.
(Unfortunately for my theory, JKR says that Lily didn't know the
effect her sacrifice would have).

Carol, who forgot to mention Hermione's missed exam question involving
an eihwaz rune as one of the Chekhov's guns she expects to go off in DH
