Miscellaneous questions after watching this week...

I am watching this week's shows (first episodes that I've watched since April's episodes) and I have a few questions:

- why is Hope living at Victor's of all places?  

- when did Maggie's place become a halfway house?

- who is Carly's daughter, has it been disclosed yet?

- where is Lucas?

- why did Victor welcome Vivian into his home?

- since Dr Dan and Carly  know each other for so long, were they both aware of the other's relationship with Victor (godson and ex-wife)?
