There's more to do with Cassie at all? Because nothing past the beginning has happened for me, and I haven't been able to figure out how to do more, there aren't any dialogue options with Cassie anymore and nothing in the logbook has directed me at all.
I haven't gone anywhere, I'm not sure how. I talked to her at the beginning of the game, and gave her a big fish, and she let me into the safehouse. But there aren't any other options that I have with her, no dialogue, and no hint pointing towards anything else to do with her, so I assume it's not there, or I completely missed something
