The Laura storyline was all about parents and children, and the latest storyline, at the moment, is about the two grown siblings, Elizabeth and Roger. Both of them are being blackmailed at once - what a coincidence! It seems clear that Elizabeth has no idea what the paintings are that Roger was asking her about, so I'd guess that they're not in the locked basement room. I'm figuring they ended up in a room that the writers haven't invented yet: the parallel time room.
I was interested to see Roger revealing himself to Jason in the basement. He didn't have to do that. Did family loyalty get the best of him? Or did he fear that Jason, having broken into the basement room, would burn up the precious paintings with one of those matches? Roger's much more worried than he was the last time he was discussing the paintings with Sam.
Jason asked Liz about her conscience. A very interesting question, and one which I have considered before. But now is not the time to think about it; we still don't know what exactly the wicked deed is that Jason thinks should be weighing on Liz's conscience.
