I don't think Chloe or Billy will tell the truth, because they don't know how. I'm hoping Jack spills the beans or somehow helps the truth to come out. This will be poetic justice for Billy, since this is the brother he chose. Cane would never have mistreated and/or betrayed Billy, if Billy had tried to meet him half way. Whatever the case may be I'm looking forward to the truth coming out in the near future.
I think chloe is going to snap after seeing lily and billy together and tell the truth just to keep the two of them apart. but if that's what happens, she won't be doing it to do anyone any favors but to manipulate them into doing what she wants. again.
Billy will tell the truth because he will get attached to his daughter. He will still not want Chloe because he will have fallen for Lily. The story line will become even more convoluted because the new person coming to town will probably be a woman who wants Cane. What a hot mess!!
