"Isaac is going to be adopted by Chris Argent."

I know that's a lie, especially given that it's stated as a fact and Jeff hasn't said anything concrete about season 6. However, I recall reading that, had Daniel Sharman stayed on the show, there would have been a story arc for him where he and Chris would eventually have developed a surrogate father/son relationship after Allison's death.

I take that information with a grain of salt though, because I haven't read many of Jeff's interviews, so I should probably look it up again to see if there's a source for it.
