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 :cozybethesda:
SquishySpaceGirl Jul 10, 2020 @ 11:49am 
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 Jul 8, 2020 @ 10:01am 
Amazing and thorough guide. You missed Valentine's opinion of The Institute, though he's probably not a fan.
YodaEedar222 May 5, 2020 @ 10:02am 
ok
Doodlemuffins  [author] May 4, 2020 @ 11:29pm 
@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...:monsteroof:
YodaEedar222 May 4, 2020 @ 10:03pm 
ya but we don't know what factions he likes and dislikes
Doodlemuffins  [author] May 4, 2020 @ 9:09pm 
@YodaEedar222 Old Longfellow has his own section towards the end of the guide.
YodaEedar222 May 4, 2020 @ 4:08pm 
can you add likes and dislikes factions old longfellow
Reidapedia Jun 23, 2019 @ 4:06pm 
cait doesnt have an opinion when you join the brotherhood of steel after the airship has arrived
