Karth House & Mary Meehan Walkthrough Part 2
Walkthroughs for Blackwell Epiphany
Entering Karth House & Discovering Mary Meehan
As soon as you have control of Rosa have her inspect and then use the door to Karth House. She will tell you that it's locked. This is your cue to switch to Joey.
Send Joey into Karth House by clicking on the door. Then have him look at the notice on the reception counter. It will mention a key and the stairs.
Once Joey has read the notice send him through the doorway on the right. If you look at the right side of the screen, at the bottom of the stairs heading up, you'll see graffiti on the right wall. Have Joey look at the Graffiti.
While the Graffiti remains the same, the word that is underlined is randomly chosen when you start a new game. Find the underlined word and remember it. This is the clue that will get Rosa into the building.
Also note that at some point while Joey is in this room a restless spirit will float by. You can try sending Joey to follow her, but he will be unable to reach her while Rosa is still outside.
