Fighting, cleaning or what?

[HughMann]

I shoot slow motion vids of the bees quite a bit and was surprised to see some behaviour I have not seen before
In the link below at 14:30 a bee lands near the rear of another bee (4 o'clock of the entrance)
It first appears to me to be grooming one spot on the bee.
But this goes on for quite some time; at 17:10 it pushes the bee away from the entrance and heads it upwards.
From 17:45 it only has hold of its wing and eventually the passive bee flies off.
Fight, clean or ...?

Looks like normal behaviour to me - perhaps a bit of interrogation of a drifter?

Drifting. The interloper adopts the submission pose - abdomen curled under the body. She is begging her way in.

Guard-bee seeing off an interloper!

Makes sense. The hive in the wall of my house is almost dead, maybe the survivors are heading to the hive
Thanks
