Also, on a slightly related tangent, has anyone else noticed that if you sneak into Billy Creel's at night even though Maggie has her own bed she sleeps spooned by him in his bed? I've always taken that as the final perhaps less subtle hint that the nature of their relationship isn't quite so tradtional adoptive father/daughter as their public discourse might indicate.
I snuck into Billy Creel's house last night to verify this.
1st attempt, 3:30: Billy slept in his own bed. Maggie was nowhere to be found at all. Billy somehow spotted me and chased me out, but not after I had verified that Maggie wasn't there at all.
2nd attempt, next night: 0:30: Billy was nowhere to be found at all. Maggie suddenly appeared behind me and seemed upset that I had broken into the house. So I left.
3rd attempt, same night: 1:30: Maggie slept in her own bed. Billy was nowhere to be found.
4th attempt, 3:30: Maggie still sleeping in her own bed. Billy still nowhere to be found.
I realize that I may have bugged out Billy somehow in the first night and that he may have gone to {0;0;0} or something. I am willing to investigate this on a reloaded game, while wearing the chinese stealth armor next time; but so far, it looks like Maggie+Billy sharing the same bed might have just been a hiccup in your game and not to be the rule.
Or perhaps they only share the bed on certain days, like Tenpenny Tower's residents and their bedtime habits.
