Actually Clark was 'observing' the situation until Trask knocked-out Dan, then the hero comes to for and he bursts in to save the day. Trask's threat with the poison gas is what causes Superman to hesitate and wait for 'the right moment'.
It's clear that this Superman has never encountered kryptonite before because in his mind the only control Trask has over him is his threats to the hostages.
The unfortunate downside is the possibility that this will cause Clark to miss his date with Lois and thus cause all sorts of annoying angst.
I'm hoping that since Clark left Gazza and Banjo at the airport, that it won't look like Clark is ditching Lois, but instead will be read as 'Clark' is missing and no one knows what happened to him.
Perhaps Lois will be concerned for him and his safety rather than think that he walked out on her.
Time will tell. (But not too much time...right?)
