I considered the facts.
What if all these series or at least 2 of these 3 are meant to have connections between them.
What if Pietro is Loki or his agent? Deceiving Wanda; knows things he shouldn't. Did his arrival set off those alarms with SWORD? What does that mean?
But Loki can now travel time; so he could be anywhere, anyone and maybe he wants more stone, powers, etc.
