Moving this here since it is more about the character than the player. :)

Albert is at the camp already. He had recently been told to "shove off" and waited on the outskirts until he noticed the bandits leaving. The perfect time to give them a taste of their own medicine.
He'll probably be spotted while trying to make it out with some loot he just got from one of the tents. So the caravan would find him pretty much red handed, trying to loot the place.
I'm guessing that, with +2 wisdom, Albert would be able to tell that the caravan people are not part of the bandit crew when he sees them. Especially when he notices a familiar face.

If it fits the timeline better, He can also try to sneak into the camp while the party is meeting Cook. Stumble upon them and be like "crap... I thought this place was gonna be empty"
Timing is a bit tricky. It is now sunset, the ambush happened this morning, so they probably had to leave last night, or very early morning. This only breaks the 'noticed them leaving' detail, since that was many hours ago.
It can have taken you time to get here after you noticed them on the road back? Or your arrival at an empty camp could be just coincidence?
It does not matter to us if you arrive before or after the crew (it is not the whole caravan, just a few volunteer guards (the PCs and maybe two or three NPCs?)). Whichever suits you better, we can do.
I don't mind, but is 'stealing' the best first impression? Maybe you are doing something else to the bandits stuff? They are also poor bandits without many resources (aside from the muscle you found useful before), so you might not have come here with the intent of looting. Your call.
