Lucas and Sarah - fan or foe?

[Beatriz]

If there's no chemistry between them, at least they could find a way to make me believe their "relationship" or why they became involved because I don't get it (ok to cover some needs would be) but what they were selling us (or what I thought) is that Lucas was "in love" (sort of). And as for Christine 2.0 I'm not sure what they want us to believe, if the answer is that she's "in love", they're doing it pretty bad.
(I put in love in inverted comas for an obvious reason :coughs: HR -> quoting almh)
