Lost in Random

Done in Fivetropolis

All locations are marked on the map, Bernie also will start yelling when you're close, and you'll see the green marks if looking in the direction even through walls

Interaction #1 (Before Gluer)
-Uh… right, to sunshine?
-Let’s go forward to the clanking.
-Sabotage the robots, kid.
-Go forwards, Bernie!
-I'm losing you
-This is a bad idea

#2 and #3 choice won't matter

To help Bernie you need to give him directions via 3 walkie talkies hidden throughout Fivetropolis. This is a highly missable achievement as the walkie talkies are fairly hidden

Here’s a video from ‘onslaught o’ showing you all the locations as well as the dialogue you need to tell Bernie:

This is a side quest in Fivetropolis that requires interacting with Bernie via a speaker system at three specific points through the disjointed city. Since you will be encountering a lot of no-turning-back points throughout that map, it will be helpful to note exactly where the locations for this quest are.

1) The first one will be just after you get through Cogwheel Paths and enter The Holy Gluery. At the end of the Cogwheel Paths, there will be three giant cogs with switches that you need to hit to stop them and be able to walk through. Once you're past the last cog and officially enter The Holy Gluery, you should hear Bernie shouting at you and can turn right to see the green quest marker against the wall. Interact with Bernie, and after a bit of initial dialogue, you will need to successfully guide him with the following specific dialogue choices:
- Uh… right, to sunshine?
- Let’s go forward to the clanking.
- Sabotage the robots, kid.
- Go forwards, Bernie!
- I'm losing you
- This is a bad idea

*Climbing the really long ladder at the end of The View is a no-turning-back point, so make sure you've done the first part of Bernie's quest before this.*

2) Continue following the storyline quest until you reach a busy area called Mystic's Quarter. Head to the right where you should see two green markers, and as you near the second one you should hear Bernie shouting again. He's in a little alcove to the right, and this time your dialogue choices don't matter so just pick whatever.

3) Again continue along exploring this area until you reach St. Alchemist Street. At the top of a bunch of twisting wooden paths will be a signpost and an NPC you can talk to (Good ol' Jackie), and just to the right of him is a short path to the final green marker interaction point with Bernie. Dialogue here is irrelevant as well, so pick whatever and get through it and afterwards you'll get a card reward and your achievement.

Your final no-turning-back point here is fairly obvious, after talking to the Alchemist and another Shadow Queen fight, when you get to another one of those "train station" platforms.
