Towards the end of the movie we see Beatrice take the SD card and insert it into the Macbook Pro. But the last time I checked Macbooks don't have SD card slots and would need an external reader to play the video clip which was nowhere in sight (if I'm not mistaken).
The hole I brought up before and no one commented on is that Beatrice opens the Fed-Ex style envelope and switches the contents. However, the adhesive is so strong on those mailers that it is almost impossible to open the envelope without using the zip opener. I work with them, and, believe me, there have been a lot of times I forgot to add something, and I have to get a new envelope. And how can Victor accuse her of not mailing the envelope if he got the notification of its delivery on his phone?
lol, people don't critically think anymore I see. She could have just used another envelope. All of the mailing info is on the old envelope, so she just copied it. Plus you just said you've had to get another envelope, so why is that a strange concept to you?
His plan was to get the Albanians to want to kill Alphonse b/c of what was on the sd card. The fact that they were still buddies let Victor know that she didn't mail the SD Card. She mailed the rabbit's foot instead, b/c he was expecting a delivery text to make him think she had done what he asked. That wouldn't give him the intended result however, so he knew she deviated...
