Why did the cat cross the road? Err... I mean the following lines seem important, but I have not quite figured them out yet. Help ....anybody?

[Ch 1] This time there would be no witnesses.

[Ch 34]  We have two minutes in  which to decide what we are going to do.
[Ch 35] He's been in there over an hour now.

[Ch 16, Richard] He looked in at a bookshop, and on an impulse bought an anthology of Coleridge's poems since it was just lying there.

[Ch 1][Ch 34] The storms of the day before, and of the day before that, and the floods of the previous week, had now abated. ... But as the evening darkened; it became apparent that the tower was not entirely without life. There was a single dim red light guttering deep within it.
(This was just before the explosion, so there ought to be 9 dozen Salaxalans)

[Ch 28, Reg] As soon as I began to realise that it was something else trying to invade me things got really bad and the furniture began to fly about.

[Ch 33, the spaceship]Occasionally it sent pieces back if it thought they would help, if it thought they might be received....

[Ch 33, the spaceship]This quiet event, too, was recorded and incorporated in the continual stream of  data processing that the ship ceaselessly performed. Not only the arrival of the door, but the arrival of those behind the door, the way they looked, the way they moved, the way they felt about being there.  All processed, all recorded, all transformed.

[Ch 35]I could have sworn you didn't have a beard before you went behind the tree."

[Ch 5] On a flattish wall of rock nearby, in fact so nearby that the Monk was surprised not to have noticed it before, was a large painting.
(Five paragraphs about this painting just passing scenery, a filler?)

[Ch 32] All of us were  aboard  the landing  craft.
(If the Salaxalans meant to colonize earth, why were they all on the landing craft on way back to the spaceship?)

[Ch 34] I would not be surprised to discover that the accident your  poor tormented soul out there is trying to reverse is the very thing which started life on this planet!"
(What proof is that there that the explosion of the landing craft creates life ...how does Dirk come to this conclusion? )
