Chatterbox
Complete all conversations with the Endurance crew.
This trophy is highly missable.
You have to talk to the Endurance crew whenever you have the chance to do so, before continuing the story. They will have a prompt above their heads if you can have a conversation with them. Just talk to them each time until the prompt disappears.
Here's a list of conversation opportunities:
Thanks to PowerPyx and JimmyHACK
Note: Sometimes characters will have dialog amongst themselves. During this time you can't talk to them. If a prompt doesn't appear when you are next to them, it's most likely that they will have some lines before you can talk.
Note 2: After you had every conversation with that character, the TR symbol will appear and game will auto-save.
Note 3: Conversation #2 is confirmed to be not needed for the trophy, but there have been recent reports that people are not earning the trophy because they either missed or skipped it. So have that conversation as well just in case.
#1 - Coastal Forest - After Lara and Whitman try to open the large gate, talk to Whitman before searching for 50 pieces of salvage. If you've already found at least 50 pieces of salvage, do NOT walk away from him until you have all available conversations.
#2 - Coastal Forest - Right after #1, talk to Whitman after you've found at least 50 pieces of salvage, before upgrading the axe. If you still can't get him to talk, upgrade the axe and try talking to him while he is waiting by the crank. - Thanks to mjc0961 for the info.
#3 - Mountain Village - You'll find Roth getting attacked by wolves. After the scene, you'll need to get Roth's bag back. Roth will give you a climbing axe when you return and tell you to climb the rocks in front of you. Instead get back and talk to him.
#4 - Mountain Village - Shortly after getting the Rope Arrows you will get back to Mountain Village and meet Roth again. Talk to him before you use the zipline and search for the pilot.
#5 - Shipwreck Beach - After the events at Gondola Transport, you'll reach Shipwreck Beach. Before you go searching for the item, talk to Sam, Reyes and Jonah.
#6 - Shipwreck Beach - After you found the item and get back to camp, Whitman will show up and soon after you'll get a new bow. Talk to Whitman, Sam, Jonah and Reyes at the beach camp, before you make your way to Endurance. Reyes is on the boat.
#7 - Shipwreck Beach - After coming back from the Endurance, talk to Whitman, Reyes and Jonah, before you go to Research Base.
. Toch een koopje!
