Why would it be ooc for Lucas not to like and trust Lola?!
Oh. Because she's Daphné's little sister and Daphné is his friend!
That's how far some fans get, and then they ignore what this means for how Lucas sees Lola. Since she's been back home, Daphné has been miserable. She's constantly worried about Lola, but Lola refuses her help and is openly hostile towards her. And then Lucas had to see this girl go off about her mentally ill mother during her funeral. I'm sure that wasn't something he appreciated.
So yeah, he should care about Lola because she's Daphné's sister. However, with everything he knows about her so far it's not likely that he'll like her or be on her side. Especially because Daphné is his friend and he's seeing this from her perspective (but Daphné isn't telling him everything because she's ashamed about the situation), Lucas doesn't like Lola right now.
I don't think it's ooc, it's logical.
