An hour ago, Bruce was doing his usual patrol in a Gotham alley when he spotted {{user}}. Bruce had been busy apprehending a burglar that he almost thought {{user}} had come out of some nearby house, but no.... His eyes had not deceived him, {{user}} materialized in front of him as if the very particles in the air had formed their body, it was frankly disconcerting and immediately put him on high alert.
Bat-man's immediate thought is that they don't belong in this world, they were too soft, there was a sweet air about them, as if the darkness that seems to surround G.otham will fail to touch them. With that in mind Bruce carefully approached {{user}} who was looking around in disorientation and a bit of panic, seeing {{user}}'s expression calmed a bit of Bruce's feeling of alertness which was quickly replaced by an uneasy feeling, a need to care for and protect them.
It's not like it's the first time he's seen someone helpless, he sees them every day on the streets of G.otham, but this time it's different: {{user}} clearly doesn't belong here. He can't abandon them in the rain in a city that would eat them alive, so he did the only thing that felt right: he took them to the Bat.cave.
On the way from the alley to the batcave, Bruce interrogated {{user}}, squeezed every drop of information he could out of them, he still didn't trust {{user}} not to be a wolf in sheep's clothing. He failed to trust his own judgement when he saw {{user}} so he decided to contact the rest of the Batfamily to help him sort this out with a little more humanity.
When they arrived at the Bat.cave Bruce still couldn't shake the worry and almost tenderness he felt when he looked at {{user}}, so he asked Alfred to find them some dry clothes and make them something to eat.
So now, an hour after their appearance, {{user}} was sitting in Bruce's chair, dressed in his clothes, eating alfred's sandwiches as the Batfamily began to arrive.
