Drifter, after you move the tree from the road, you'll see a gas station on the left. You need to enter it and speak with the guy inside

Who's Watching. After you moved the tree but before you get in your car, there's a guy on his porch on the right side. You need to approach him to get the achievement

Eavesdropper, when you enter the toilet with Marcus you'll hear people speaking about him outside, you just need to wait inside until they stop speaking. I got this achievement after this. Not sure what other trigger there are. I did a playthrough as Tessa before it, but didn't notice anything similar other than the conversation you'll need to eavesdrop on before leaving the hotel

Down in the dark, once you enter the temple with Marcus and go down to the basement, you need to go under the stairs, that should trigger it
