The gentle movement of Archie's hand with his was soothing to Wren and it was silly how that small gesture could mean so much to Wren, just holding hands and swinging them. Then again, he hadn't really been properly touched in a very long time and, despite what he'd gone through, Wren was a hopelessly tactile person. The plan sounded good to him, what he understood of it, and he nodded happily. "Yes please!" although he would have been happy to do nearly anything.
He started moving as soon as Archie indicated, obedient as a dog but more joyful than the waggiest tail. "Oh, I can, what you like." He said, unsure and honestly willing to do as Archie saw fit; regardless of his circumstances before he ended up as a test subject for Area 52, Wren had become so used to doing as he was told that the idea of making choices now was a little hard for him, nevermind the fact that they seemed to fold out infinitely before him. He'd need a bit more socialising before he could make big decisions such as did he want to go to Archie's or back to the woods after getting milkshakes; his little brain was going to explode when he found out milkshakes came in flavours. He wasn't bold enough to tell Archie he didn't really care what they did as long as he got to spend time with his new friend.
