He took a few steps back upon seeing the knight having his hand on his hilt, ready to draw if he screwed up in some way. Realizing that it wpuld not be a great idea to attempt and pick up the knife, he wouldn't want to risk Arcturus thinking he would attack him.

"I live here, but I forgot my key when I left, earlier today, and now it seems like the door's jammed"

He motioned to the door as he spoke, gently pushing it with his left hand to make sure it wouldn't open.

"I can prove it, that I live here, There is a drawing of me and my parents in there, several drawings. They are in a book in the common area, next to the fireplace"
Robert
*Arcturus would watch his body langauge as the Tiefling spoke. He took note of his body langauge, spotting a little hesitancy. His words came off somewhat truthful to him, although the light push on the door came off strange to him. Almost as if he was trying to see if he got it open. He'd take a step towards him, slowly, attempting to make it natural in conversation.* 
"Any proof that wouldn't require me to manually force a door open? A neighbor, proof of ownership, mail. Anything of that like?"
Whitney
Skalyre closed his eyes for a few seconds, taking a few deep breaths and regaining his composure. In his mind he reminded himself that he should remain calm, definitely in this situation.

"Right, mail."

He said as he took a few steps back, where his mailbox would be located. With a handful of letters in his hand he walked over to Arcturus, handing him the still closed envelopes.

"One of those is a mail from my father, Kilmus, adressed to me, Skalyre. Open it and see for yourself"

Arcturus would have been handed 3 envelopes of Skalyre's mail.
Robert
*Arcturus would release his grip on his hilt, reaching out with the same hand and taking the 3 letters. Normally, he wouldn't open another person's mail, out of respect for them, but here it unfortunately became a requirement if he wanted to prove their identify. He'd take the letters, opening one at a time, quickly skimming it looking for the letter addressed to him from his father. The fact that he knew these were here made his story much more plausible, if he finds the information he is looking for. If not, someone will be heading to the capital's jail for the night.*
Whitney
In one of the letters there would indeed be a message from Skalyre's father.

"Dear son, I hope the city is still treating you well. It has been a few months since your last visit, could you try to come over when you have some time, the neighbours are starting to miss you. With love, your da."

The other letters would be some notifications about his taxes and an invitation to a party of one of his friends.

Skalyre looked at the knight awaiting his response.
Robert
*He'd review the letters, taking note of his taxes nearing their due date, as well as the invite. He'd quickly place those two back into envelops, before opening the third and final one. He'd skim it, seeing that it was indeed from a father. While the name wasn't on the letter, it was evidence enough for him. Returning it to the envelope, he'd approach Skalyre and hand the mail back to him.*

"Checks out Skalyre. And it appears you need to take a trip for your family." 

*After handing it back to him, he'd take a step back giving the Tiefling some room. Looking back to the door, he'd take note of the lock. It was familiar to him, specifically he knew how to force it open without destroying it.*

"Would you like a hand with this door? I've seen this happen enough to know how to open it back up"
Whitney
Skalyre grabbed the mail, reading the letter his fathet sent.

"Ah, indeed, I should visit soon"

He said before the Knight offered his assistance in opening the door, to which he happily nodded.

"That would be great, it's not the first time it's stuck, but now its just completely wedged in there. I had planned on getting a new one, but so much to do, so little time"

He laughed softly in a friendly, calm tone as he spoke.
Robert
*The knight would nod, grabbing his hilt and drawing his sword. In his offhand he'd grab the door hilt and pull the door towards him, ensuring that it was fully closed to help the lock slide back into the lock when he unjammed it. He'd take his sword and shove it into the slot between the door and the doorframe, directly above the lock. He'd ensure it was in there, before letting go of the door handle and with his offhand placing it ontop of the sword. His armor would protect him from cutting himself in this manner. With his hands in position, and his tool in place, he'd drop his weight on it, pushing the blade down and sliding his sword inbetween the lock and the doorframe, forcing it back into door. Giving his sword a tug, he'd pull it out, the door opening towards them. There was minor chipping damage due to shoving a sword into the door, but it was open at least. He'd catch the door and stop its motion, taking his sword and returning it to his sheath. Turning towards Skalyre, he'd give him a nod.*
Whitney
Skalyre would anxiously wait for the knight to open his door, his posture quickly changing as he saw the door open. He smiled and gave the knight a nod as thanks before making his way inside, first grabbing his key and then looking at the damages on the door and if he could see how it had jammed.

"Yeah, now I have a better excuse to get a new one that doesnt jam every other week."
 
He sighed slightly before walking out and looking at the knight.

"But where are my manners, how about I repay you with a drink after your shift, how does that sound?
Robert
"Yes you do." *He'd say in response to his comment, watching as he went in and came back out.*

*After hearing his reply he'd mentally sigh. Aasimars couldn't get drunk, the ale actually tastes like shit to him, but that's quite alright. Giving him a nod to his offer.* 

"Sure, why not. I'll be off in a few hours. Do you have a specific place in mind?"
Whitney
"Well, I will be in the hungry wolf later today, thats where I usually spend my evenings"

He looked at Arcturus and awaited his reaponse. He had learnt that Aasimars couldn't get drunk, and would be prepared to buy him a drink that Arcturus actually likes.
