The point is that you've suddenly claimed he's worrying about his ex, an ex that didn't cost you a thought really beforehand, but now that Siavash is acting with remorse you'll choose to defend him over it. It's a contradiction which is further highlighted by your willingness to lambast Noirin over her fling with him and to criticise his ex over her antics. There's no logic to it. You'll accept anything that Siavash says or does, even if it totally refutes your claims from earlier on in the series.
