It is pretty obvious that HKS isn't the father of that baby. Good lord, did you see his nose in all of those closeups. However, I do think he will be devasted when the baby is taken away from him. Many of the players in the sage seem to be "out there" to some degree or another.
I think it is a definite concern that HKS might pull one of those kill the baby and then himself deals if it looks like the kid will be taken away.... which, IMO, is inevitable. There is no way he will be allowed to keep that baby when all is said and done with the DNA testing.
I don't think that HKS could off himself.
What concerns me about HK$ is that I think (from seeing his red, bleary eyed photos) that he was/is a drug user also. Not at the level that he kept ANS at, but a user none the less. I also think that much of his eratic behavior, weird reactions, has to do with him not doing drugs right now (so as not to have drugs in his system when any DNA testing is done). Between the grief and the drug withdrawal, I fear HK$ is very fragile and volative and could just snap...DanniLynn needs a guardian ad litem asap.
