No, he meets her for the first time, and they get along well.
And she compliments Bellamy to Clarke, because even though it's an AU, I thought that would be pretty in character. Rewatching season two did remind me how complimentary she was of him.
I feel this strange compulsion to write happy/good things for Lexa in my fics. So even though she's not a major character, what you do see of her is . . . it's nice. It's good.
