My hope is that he'll give attention to the other girls once he does his own playthrough. I'm still a bit miffed that Mindy and Maggie got content instead of Laura and Amy a little while ago.I think Sarah should be taken out of this list... bon already said she's the one that's going to have way more scene later (probably main quest).. Jet i dont know how he's planning to work on her, since she's tied to warren (maybe later too).
Sandra - Beth- Christian - markus - Daisy can be finished easily i think, unless he ties christian and Daisy to main quest or warren path.
Ronald? isnt that guy on jail lol ... if you mean "helping him" on the Miss taylor thing on the first part of the game, i hope Bon doesnt go that way back for just a side character that doesnt have nothing on history lol.
Shasha depends on how he's going about her, if he goes on the "Shasha route" instead of Sarah, this updates needs to be pretty worked since a lot of things would be locked and Sarah is like a pretty important character for when lucy enters the history. if he goes on the "Make them friends again", he can make a good update on her but nothing that takes way too much work.
Laura and Amy.... fuck man, i dont even know why we still dont have nothing on them, but the way the updates are coming, it seems that they will be the last one of the side characters.
Since he's going to play the game himself, maybe he will change he's mind about how the characters will be updates.
If Beth is in 1.5 my bet is that either the entire Daisy/Sandra/Christian questline will get finished (Rather, Sandra and Christian since Daisy is apparently getting finished in the Xtra version of 1.4) alongside her and maybe something else. MAYBE Markus' family will get content? Who knows. I really don't care for a Ronald route though. That's one quest branch, probably the only one, that I wouldn't mind BoN forgetting or dumping.
