Hassan will venture out himself? That's bad news for Ibrahim - Ibrahim doesn't know where he stands with Hassan, which will mean at least some hesitation. Hassan will clearly not hesitate...
Then again, Hassan is of an advanced age. He might have to kill with subterfuge, rather than stabbing Ibrahim on the spot of their first meeting. If so, Ibrahim has a slight chance. Perhaps he will be wary enough that it will take Hassan a while, which gives time for error or outside intervention.
My personal preference? Arzu cottons on to Hassan and stabs him dead while he is completely not expecting it. Perhaps while he's not even aware she's there, while he's amiably chatting with Ibrahim, trying to deceive the latter as to why he is coming to visit him. Yes, that would be nice. Highly unlikely to happen, but nice.
