Games : Book 2: How do I get Abby to talk to me in Chapter 4: Dreaming?

In Book 2 of Dreamfall Chapters, I'm stuck in Chapter 4: Dreaming.

I have two quests going on:

1. Bring some information to Mira, but a bot is fixing Mira's front door and the game tells me to come back later.


2. Find information about Abby to get her to tell me where I can find Hannah.

The problem is, nothing in the room Abby is in tells me anything and randomly wandering around town hasn't helped either.

There's are four manhole covers I can remove. One is welded shut, one is stuck partway open (too small for my character), one is watched by a policeman who threatens to arrest me, and the last is where Abby is.

How do I find the information to get Abby to help me?
