I was confused about this. Because Anna made such a big deal over Ryan's kid being the first hybrid. Does this mean that Tyler is just increased with hormones or chemicals or something?

That's an interesting question, and it would highly seem like it. Isn't Anna trying to get Lisa to kind of make Tyler sort of impregnate her because she's fertile while Anna no longer is? To breed sturdier hybrid soldiers with a high level of phosphorus would ensure a stronger survival rate. It makes sense with this entire Red Rain situation.

Me too! I loved Joshua, and him just not remembering is just sad indeed. :( Lisa seemed terrified by this as well. I keep hoping it's a ruse, but I'm not entire sure.
