Wolfe could tell by Mallaidhs reaction she was upset at the thought of her sword being cursed. Wolfe could relate, his grandfather had a large collection of antique firearms-still functional. Given the same circumstances... Wolfe wouldn't want to believe one his grandads prized possessions were used for...this.
"I apologize, I did not mean to upset you ma'am," Wolfe said.
"I am fairly sure that is your sword.... Just not... Your families sword as you remember it."
Confused looks came his way. Wolfe thought for a moment then spoke again.
"Imagine, a large bubble," Wolfe said, he got up to a white board and drew a circle, he made random dots inside the circle.
"Ok, imagine this is a bubble, on a three dimiensional scale, so there would be dots next to, behind, above, and so on and so on with every other subsequent dot, this large bubble, is called the Multiverse" Wolfe looked around making sure he was still be followed.
"Now, each dot, represents individual universes, mine, yours, everyone's. They are independent of each other, never connecting, but still follow at a parallel rate. Contrary to popular belief, time is not linear," he drew a line and imedietely crossed it out, "instead...its spherical. Like when your on a plane going to the other side of the planet, um," Wolfe looked at her clothing and remembered she probably doesn't know what a plane was.
"Um, a large ship going accross the sea, you look out to the horizon you see a natural curve." Hirsch actually appeared to be paying attention, which surprised Wolfe. He always knew Hirsch was a good warrior, hell, one of the best, but Wolfe always felt that Hirsch was...simple, to put it politely.
"At some point," Wolfe drew lines from one dot to another "there was an...event? Somehow, someway individuals from these independent universes, and times were transported, across time and space...to...here," All the lines intersected on one dot, his dot, only four years later.
"Now to answer your statement ma'am," Wolfe went on.
"Just because you knew your families sword in your time," Wolfe pointed to one dot, then moved the marker around the bubble then a sharp downward angle to the intersecting dot.
"Doesn't mean, that in between your last memory of your home, and waking up here, years if not centuries may have gone by in your universes, and that sword made its way here...to my world... Four years ago, and to me, it feels like yesterday, because subjectively it was yesterday."
Wolfe finished, looked to Hirsch and asked "You got anything to add Joe?"
Hirsch looked to Mallaidh and spoke directly to her.
With a giggle and a sheepish grin, "you got pretty eyes." 
Whack!
Hirsch recoiled from the blow that Wolfe delivered to the back of his head.
"Fraggin moron!"
Before Hirsch could speak his eyes widened.
Something just walked in the room.
"Holeeeshit! It's ma'fucking Goliath! Bruh I loved your show as a kid!"
WHACK! This time it was harder.
"Owww man! Whiskey tango foxtrot asshole!?"
"Stow that shit you simple dumpster baby."
Hirsch scoffed and sat back down.
Wolfe walked up to the large creature, his eyes conveyed two things to Wolfe, intelligence, and kindness.
He held out a hand to the creature, "I apologize for my SAW gunner, he's a idiot with no filter, but probably the best human being to have on your side in a fight. My name's Wolfe, Corporal Wolfe, but you can call Wolfe, and that's Hirsch, as I call him numbnuts."
