It is not a good idea to have a varren in a confined space.
Shepard learned this the hard way. She had her arms locked around Urz's broad neck to stop him jumping about the place. It seemed like he remembered Garrus and Mordin, as was keen to show it by jumping on them and nearly eating half their faces in his excitement, something witch Garrus strongly disapproved of.
Garrus and liara took Mordin up in the elevator to the Med bay.
"Alright Urz, we are on a space ship, try not to break anything, ok?" Shepard said to Urz. As soon as Shepard began to let him go he flew from her grasp and proceeded to run riot in the shuttle bay.
"Whoa!" James exclaimed as Urz knocked into him causing him drop his favorite hello kitty mug, shattering on the floor. "Lola, what was that?"
"Your new roommate." Shepard smirked, folding her arms.
"No. Hell no."
"Why not? I'd finally get someone to talk to." Cortez teased.
"The man does have a point." Shepard ribbed. "Besides he can be useful. Urz, clean." She indicated to the smashed mug and it spilled contents. Urz obligingly licked up the spilled liquid.
"Are you sure that was wise commander? That was coffee." James asked picking up the shattered pieces of pink painted porcelain.
"He'll be fine, look he is fine." Shepard gestured to the varren who was idly scratching its face with a hind foot.
"Who's a good boy?" She patted Urz affectionately. "Gotta run, reports to file, Reapers to annihilate, things to deliver, generally being a glorified postman.." There is more to this list but she was cut off by the closing elevator doors.
As Shepard reached the bridge she called out "Joker-"
"To the Citadel!" Joker interrupted. "Ha, beat you to it. Course was set as soon as the shuttle boarded."
"I should give you a biscuit." Shepard joked.
"Yes you should, we'll be there in a hour. Hey, since you're going down to the kitchen mind bringing me a sandwich?"
"That is not Shepard's purpose, Jeff." Edi said.
"I know, but it was worth asking right?"
"Nope, see you later Joker." Shepard wandered back to the elevator.
"We're here Commander, incoming message." Joker said, "No kidding? Shepard it's Thane, he says Cerberus is trying to take over the Citadel."
"Figures."
