In the text message screenshots, there's a conversation about asking his wife to keep her IV port in, and to not remove it. He claims it's so that he can give her medication to help her feel better. But it's just the most bizarre request, clearly he was hoping if she kept it in he could kill her in a much more subtle way using the IV port.

Also there's a text message where he messages his business partner Ryan after Ryan goes to the police about the arsenic. And it's very narcissistic and selfish. In fact all the text messages snapshotted, between his wife, friends or business partners are an interesting insight into the mind of a psychopath and it's kind of scary to read.
