Thundercracker gives Frank a small grin as he slides past through the door so Blurr can close it. "It's all right." The grin quirked up higher. "He just takes after his owner." Turning a bit more serious, but with the small grin still on his face, he offers a hand to Blurr. "It's good to see you back on your feet, Blurr." He's still not used to mechs - or anyone else - being killed and coming back, so it will never NOT be relief when someone recovers. Especially someone important to him.
