After Tails is almost literally ripped to shreds while defending the outcasts from Rakghouls he passes out. When he wakes up he finds that Carth has been waiting for him. It becomes heartwarming when you realize that they were on a time-sensitive mission and yet, Carth took the time to stick around and make sure Tails was alright.
After Tails' duel with Bendak, he flees back to the hideout and curls into a ball. Then he gets a verbal ass chewing from Carth and Bastila. The poor boy is an emotional wreck at this point, but when he wants to just go to sleep, Mission offers to sleep beside him. After minimal grumbling, Tails accepts, and Mission snuggles him for comfort. Tails really needed someone to hold him right then.
