Behemot vs Puck - the dynamic

[clem131]

Ok, please help me make sense of this, 'cause nobody talked about it at all and I feel the only weird guy in the bunch who didn't get the obvious explanation.

Here's a scheme of the layout of things the second after Carl's death:

Gate 1 | Behemot | Gate 2 | Carl's corpse | Puck | Gun Truck

I hope we all agree on that. The behemot reaches through the gate and kills Carl, so at one point there's one gate and Carl's corpse between Puck and the behemot.
Then the behemot goes to the truck and smashes it, then he smashes Puck, then he dies.
What happens in between drives me nuts, I can't find a scenario that makes sense.

We go from the above scenario, i.e.
Gate 1 | Behemot | Gate 2 | Carl's corpse | Puck | Gun Truck
to this scenario:
Gate 1 | Gate 2 | Carl's Corpse | Puck | Behemot smashing guntruck | being-smashed Gun Truck

Notice how the behemot goes from left of puck to right of Puck. Please note that any actual pathway, any shape, any actual distance won't matter in this schematic: whatever the shape of the building and the parking, at moment A Puck is beween the behemot and the truck, and at moment B the behemot is between Puck and the truck. Both want to get there ASAP. They will then follow the most direct path.

Here's a (non-complete) list of things I don't get:
- why does the behemot pass over Puck without harming it. Or does it?
- if it does, why Puck doesn't mention the pretty frakking important detail "he passed within inches of me to get to the truck and he didn't harm me when he was so close he could have blinked me to death with its eyelids."
- How does the behemot get out of Gate 2
- if you answered "by smashing it" then here's what happens next: Ink leaves Puck, goes back to the entrance, passes the gate the behemot shattered by looking at it and carefully closes the other identical gate so that... the wall-and-gate smashing behemot won't get out. This applies also to Tanya's little hand-waving of 43.1.
- again if you answered "by smashing it", why they didn't get out of the jail sooner, being starving and all. You get hungry and desperate, you smash 4/5 little walls and you're out.

I'm not being sarcastic, I just don't get how can I be the only one not getting it.
Thanks to everyone who can help me understanding this.
