After riding the bucket-line down from the tower, you’ll find yourself back in Momo’s apartment. Walk forwards, over to the TV, and B-12 will notice a note. It will inform you that Momo’s down at the bar, and that the window is locked — but the note includes the code. From the TV, turn right and you’ll see a keypad near the window. Walk over and use B-12 on it, and after a failed attempt, he’ll get the window open for you.

Jump up to the windowsill, and then down onto Momo’s porch. Slip through the bars of the guardrail and jump into the bucket, which will take you to the center of the now-familiar slum rooftops. Walk straight ahead after exiting the bucket, and look over the edge — you can see just the entrance to the bar in the alley below.

Cat parkour your way down to the street and find Momo in front of the bar — he’ll speak to you and tell you he’s found a signal. Finish the conversation and follow him into the bar. Hop up onto the stool next to him, and enjoy the cutscene/conversation — you’ll get a fairly sizeable lore dump. Once the cutscene ends, follow Momo out of the bar and around the block to Seamus’ place. After Seamus won’t open the door, Momo will pull a wooden board aside and open up a path for your little cat bod to slip through.
Head into Seamus’ apartment and approach Seamus. He’ll shout at you — show him his dad’s notebook and he’ll relax, and you can start searching for the secret lab.
Once you unlock the secret lab, you’ll head in with Seamus. Next, you need to find something useful in the room.
Once you’ve found the hidden object and shown it to Seamus, follow him as he goes to unlock the door to his apartment. Head back outside — now you’ve got to find someone who can repair the object. You can show it to folks around town and do some exploring, or you can peek at the solution below. Note that this is one of those “If You Give A Mouse A Cookie” puzzles — you’ll ask someone for something, and they’ll say “First I need X”, and then in order to get X you have to get Y for someone else first… you get the idea.
After exiting the place you got the Tracker fixed via the window-shade shortcut, you’ll find yourself back in front of the bar. Go straight past it (towards the stairs) and turn left at the stairs, then turn left again to head back to Seamus’s apartment.

Inside, speak with Seamus and show him the Fixed Tracker. A cutscene will play, and then you’ll need to follow Seamus as he follows the Tracker’s signal. You’ll make your way to a sealed door, Seamus will open it, and you’ll hop on through like the brave little kitty you are. Follow Seamus to the next door to start another conversation, and he’ll give you the Outsider Badge.
End the conversation when possible, and he’ll open the way forward for you. Continue forward, and you’ll soon come to an area where you can turn left or right. By going left, you’ll find a Memory up against the wall. You can then go the other direction to enter the Dead End!
