0 | Same reasoning as the other two - I would have agreed that speed=tb, but warm is not the same as warmblood.
Look in the mirror – we are the same. Appearance reference: "Look" to refer to eyes, "we are the same" - Grim and Iona both have green eyes.
+1 | Eye colour was one of the things I was looking for here.
Such bravery impassions your heart. Personality reference: Straight from her profile: Iona is brave and passionate.
+1 | Yep for personality
Though there is nothing else special about you. Magic reference: "Special" to refer to magic, Iona has no personal magic or abilities.
0 | Similiar to blu's comments - there are special things about her. Her coat isn't plain, her species isn't plain, she has items, has a rank, etc.
2/3 is a fail from me.
