I don't think that the girls having the basement room as their bedroom is a negative in any way. I've seen that enough times in my lifetime that it doesn't strike me as anything to pass judgment on. And the only reason why I would have an issue with being in a basement room by myself is that 'house settling' and other noises seem louder there. Generally, I think the whole uproar over the girls having a basement room is one of those tempests in a teapot.
I don't see why it matters how the SF acquired his truck. I also don't think it matters what he does all day since he doesn't seem to have a job. Lots of spouses don't work, and I don't see any reason to question what they do all day either.
I'm still not sure about the 'blanket' thing. I'm going to wait until I hear from LE that Celina was wrapped in a blanket before I accept that as fact.
I'm not attaching any importance to comments made by the biological father, partly because he's more of an outsider than anything else, but mostly because I don't have a high opinion of the kind of reporting that goes on while cases like this are unfolding. Reporters want the most tantalizing quotes possible in their stories to hook readers and keep them coming back for more, so I take the snippets they've chosen with a grain of salt.
