Looks like the bonus story is part of the main path. She has the tattoo.
Ellie's tattoo? Well it would look odd if she didn't have a tattoo in the main story, but did in the bonus.
I'm not bitter at all : /
I just think that's how it's logically progressing and would follow the [relative] realism of the game so far. If not the last day, then very close to end. I would be disappointed if the slow-burn nature of the game descended into a generic porn-a-thon with Sophia banging anyone with a pulse.
Ahh. It was the "only one character" that I was having issues with, considering I'm looking forward to the GW Threesome on the Lesbian route, that L&P talked about in the beginning. But yeah, the porn-a-thon gangbang that some are expecting doesn't appear to be L&P's style.
Be careful with logic. Back in the day it was completely logical that the Earth was flat and the centre of the universe. But we now know by experiment that this is not true, and never was. L&P has a knack for presenting information that leads us to one conclusion, and then throwing us a curveball when updates come out.
