Did a playthrough not talking to anyone

In May 2013, I did a default ME3 playthrough without talking to anyone to see what changes. In Oct 2014, I decided to do the same with a save import and with the Citadel dlc completed

Crewmembers

Cortez - Shepard will never learn he was married. He dies in London if you don't talk to him on the Citadel. He will not have a meetup in the Citadel dlc

Traynor - Shepard won't learn that Traynor was on Horizon when the collectors attacked. You won't know about Grissom Academy leading to the deaths of the students, and if Jack is alive in ME3, she will be killed on Chronos. No mission about rescuing the ex-Cerberus scientists, and if Jacob is alive in ME3, his name will be on the wall after finishing Chronos.

It will be edi that tells Shepard about Kai Leng going to Sanctuary and not Samantha. She still gets credit for tracking Kai Leng. When you first see her in the Citadel dlc with her toothbrush, Shepard will ask about it. Here's a video. Thanks to cap and gown. She will have no meetups in the Citadel dlc

During her goodbye scene she has this to say "Its all right Commander. Its a little late to request a transfer now

Adams - he won't inform you about needing a GX12 Thermal Pipe

Dr.Chakwas - she will not tell you about needing the medical supplies from Tactus. Shepard also won't be able to have a drink with her. If she isn't spoken to when seen at the hospital, there will be no doctor on the ship

Ken and Gabby - they will not get together

Joker - his dialogue is the same. He will not have a meetup in the Citadel dlc

Kelly - If you don't talk with her, she will die during the coup


Squadmates

Garrus - you don't shoot the bottles with him. The goodbye scene is the same and no meetup in the Citadel dlc

James - he won't come up to the cabin to discuss a mission involving the Collectors.The goodbye scene is the same, and he won't have a meetup in the Citadel dlc.

Javik - his goodbye is the same as if he never touches the memory shard. No meetup for him in the Citadel dlc

Liara - she won't come up to the cabin and show you the time capsule. She won't meet her father. No meet up in the Citadel dlc. In her goodbye scene she will not offer her gift

Tali and edi - their goodbye scenes are the same and no meetups in the Citadel dlc

Ashley - she can be shot during the coup and if you don't shoot her, she will not come back on the Normandy. In this playthrough, I brought her back on the ship. Back on the ship I never talked to her. Her goodbye scene is still the same. No meetup in the Citadel dlc
I imagine it would be the same if Kaidan is in your playthrough

Anderson - he will say "I was born in London" only once

Grunt, Zaeed and Kasumi - by doing there related mission, they will have a meetup.

Miranda - she will die on Horizon

Samara, Jack and Jacob - if Shepard doesn't talk to them on the Citadel after doing the mission involving them, they will have no meetup in the Citadel dlc

Thane - if you don't see him in the hospital after the coup, there will be no message to invite his son to have a memorial for Thane in the Citadel dlc

During the evacuation scene, it was Ashley I talked with and her dialogue is the same
