I have a better opinion about Cross then you
He has a calculative mind (supposedly) that is capable of predicting Allen's actions. After all, the core of Allens personality is still the same as it was when Cross adopted and educated him so I do not see anything that could prevent Cross from predicting Allens actions. Also, General does not seem to be troubled by anything as he would be if noticed Allen changing for the worst, so I guess his opinion about his student haven't changed. He still trusts him.
