Of course DPC doesnt want to reveal that yet, but its just stupid that MC doesnt notice the house on the pictures and doesnt even ask himself a question like "huh, strange, its the same house isnt?" Its outrageous. And now he is even going INTO this house without wondering about it... its... argh, forget it, there is no word to discribe how stupid that is. Not the first though that DPC makes something stupid like this in the game just to cover a major plot some time longer, which throws the question up... why revealing the Lynette picture anyways so early on? There was no point in that. Just let the picture be in the box and later found by Neil or something like that... Whatever.
Regarding the house, it is revealed that it was baught by the royces about the time when Lynette died. Geoff (btw no ruccus in the thread about the fact that man-bun out of ep5 is Jills father... well it doesnt matter anyways right?) said they baught it from Manyards, which is Biancas Family... which brings me back to Lynettes picture. The reddish woman there seems to be related with Bianca Maynard. Maybe not Mother, cause Bianca is in her mid-twenties, the picture is about 19 years old and the girls where about the same age in that picture... so between 18-21 i guess. Which would mean that if the picture shows Biancas mother, that she is a teenage mom, dont think so... more likely aunt. So Lady (aunt) Maynard is on that picture together with Lynette and the black hair Lady who could be about anyone. Maybe a Royce? Certainly not Amelia though... Amelia misses some important "marks" here. The blackhair woman looks like the "Vixen-emo" girl, her daughter maybe? So far the black hair girl on the picture isnt important, that might change.
So yeah iam pretty sure, the reddish lady on the picture with Lynette is a Maynard. The black hair Lady can be anyone... and its kinda obvious with the makeup and the ridiculous black hair, that the hair is dyed... so she very well could be a blonde or whatever.
