If Ian is unable to give what he is providing Cindy. I don't think Cindy is going to stop herself from getting same thing from somewhere else. I know Ian connects to her on deeper level than others(Wade included). This same thing is a double edged sword and going to cut whether it's on one side or other. Like imagine if Cindy is feeling emotionally overwhelmed and Ian is on trip and Cindy is in Wildcats shoot (some type of scenario), how longer can Cindy keep herself in check with Axel around.
If stars align than Wade is again in a fucked up position and this time Ian is directly responsible of that "exploitation" bcz it was all alone started by Ian himself. Axel is always in a better position than Ian in term of "RED STRING" without consequences
