The One Who Knocks

I don't see the similarities to his sister.
He is really handsome though.
In some pictures they look more alike that others.
These ones in particular, I find, see them have an uncanny resemblance of one another.
In others, particularly when Alex is on his own and has his hair styled in some manner, the resemblance isn't as strong. The main feature which separates them is his jawline and chin being much more pronounced and sharper than hers his, but the shape of their eyes, nose, and mouth are quite similar I feel.
EDIT: Oh I see you've searched more. I would agree that their eyebrows are also similar.
EDIT 2: Also I love Donal Skehan.
