just your shadow on your floor

[Karlach Cliffgate]

You don't actually know what she is hinting it, or what she is saying - only taking in the words that she is actually saying out loud, that she thinks that Astarion and Imza are interesting company to have. They are. Everyone is interesting on their own, to be quite honest; they all make great company, some more and some less. Even someone like Wyll who has wanted to hunt you down and kill you. Even someone like Lae'zel who never seems to enjoy all of your companies but still sticks around (mostly because there are the tadpoles).
You do follow her, though, step by step, like a moth to the flame being drawn by her very light.

What does 'interesting company' mean? Good, bad, both?

You have never really thought much about good people, bad people, at least not those you encounter on a daily basis - you do think there are bad people in this world. You think about Gortash, you think about Zariel, you think about these goblins who would have attacked the grove and spilled the blood of innocents, dozen of them. But in the end, people like those around you, they have their own motives, their own goals, their own reasons. Plenty of them good, plenty of them bad, and a ton of secrets each and everyone is carrying.

Hopefully not another Shadowheart-Lae'zel-situation.

Where they have tried to kill each other.
