As welcoming as Cali's house can be when he wants something from you, there is often a cost to interactions with Cali. I wouldn't want people to be misled. He employs assassins. He has no compunction about ordering people killed. He may seem friendly to the rebels, but he also planted spies within their organization, and even suborned Mariah to as in that capacity on his behalf, potentially getting her in lots of trouble.
So, when he is courting you - as he was Trax - he can be very welcoming. But he is also someone who can, through his people, wield a knife in the dark.
No one has really probed his motives or morals much, so keep that in mind. Cali has an agenda that you haven't probed yet. He may not be all he appears to be. Or, perhaps worse, it may be he is exactly what he appears to be - the powerful leader of an extensive criminal syndicate.
