So episodes 3 and 4 have been quite interesting for Ken.
In episode 3 he defends us which is very admirable (although arguably not quite so 'omg amazing' as he does force you to take the radio in the first place, but I digress).
He also becomes more unstable, and this continues through most of episode 4, in which he is angry at clem.
But then he calms down when the baby comes into being, and he'/s happy (ish) and has something to fight for again. But this poses a bit of a problem.
In a life or death situation, who will Kenny prioritise? Because right now his entire mental state rests on the baby, and as a result of that it seems like he could well try to save it over clem now.
I'm not sure, but I honestly can't see him sacrificing the baby for, well, anyone.
