[Doodlemuffins]

Updated!
Changed Danse's response to the Deathclaw Egg to dislike instead of hate.

[Dalek soldier]

Turns out Danse also dislikes giving the Deathclaw egg to Wellingham in The Devil's Due. Though it's just dislike, not hate.

[Doodlemuffins]

@Dalek Soldier
Thank you! I updated the guide!

[Dalek soldier]

Update for Porter Gage.
Drink Alcohol ❌
Modify Armor: neutral
Modify Weapon ✅

Update for Cait:
Convincing Bobbi to leave in The Big Dig ❌

[Neila]

Excuse me, maby I'm wrong but... Curie has an X in Railroad faction? Isn't the ones who helped her become who she wanted? And, she never showed "dislikes" when i did many many quests for them. Perhaps You mean something with the main plot, which i didn't finish yet. I just wonder. BDW, nice guide

[SquishySpaceGirl]

Cait doesn't bat an eye at murder, Cait also likes it when you launch the artillery at the castle for the first time.

[darkconfuse]

Amazing and thorough guide. You missed Valentine's opinion of The Institute, though he's probably not a fan.

[YodaEedar222]

ok

[Doodlemuffins]

@YodaEedar222
Ah, the reason Longfellow doesn't have any factions posted is because he appears to not have any opinion on any faction except the Children of Atom.

As far as I can tell...
Longfellow does not like any faction.
Longfellow only dislikes/hates the Children of Atom (and/or if you raid settlements with the Nuka-World DLC)

Sorry I don't really know anymore about him...

[YodaEedar222]

ya but we don't know what factions he likes and dislikes
