Re: He ''flicked it open''
There is nothing missing. Do you understand what I mean when I say "He kicked the door open", which could be shortened to "He kicked it open"?
This might help - here is a video of a man "flicking open his Zippo lighter" (ignore the rest of the video after the first couple of times he shows at full speed and in slow motion how he opens it).
He has a lighter. He flicked his lighter open. He flicked it open.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
