Jackie stealing the monkey(s) is way too convenient for Alex B.
At the exact moment there's uncertainty over whether there's one or two monkeys, Jackie comes in the night and takes it (or them).
James Drake kept saying they took "the monkey" and Alex B said "monkeys." The monkey we saw earlier in the day with James Drake was obviously Luna and they were calling her Benji. Alex B wants us to believe she took both monkeys, but it was only Luna.
All I'm saying is that this works out very well for Alex B's delusional narrative. There's no more "Where's Benji?" messages to block. Was he in on all this? "Jackie, come take the monkey and make it look like a robbery, I won't press charges."
According to Alex B, he's not pressing charges. Jackie's mistake was messing with James Drakes and Alex B's new BBL Melissa, and they are pressing charges.
