Heartwarming / Things We Don't Tell Humans

• When Jazz and Prowl finally Bond after reuniting on Earth.
• Ratchet adopting Prowl and later the Terrible Twins.
• Megatron and the hatchlings.
• Sam's theory on why him and Faust are so close: while Sam is the reincarnation of a Cybertronian Faust got the human soul Sam was originally supposed to get.
• Sam forgiving Starscream within the afterlife and promising that when he and his trine are ready all three will be reincarnated.
• Soundwave, upon being shown that there are Sparklings, getting his Heroic Second Wind and working to stop Sentinel and Dylan.
  • The first thing that begins getting Soundwave to fight the programing that has been corrupting him? The knowledge that Blaster found Frenzy and Ravage and has worked to repair them.
• Laserbeak swearing allegiance to Carly and protecting her from Dylan. Especially when he and Soundwave learn she was sexually assaulted in her youth (with both horrified they put her in that situation)
• Soundwave and Blaster declaring that due to her soul Carly is a "Carrier", a special breed of Cybertronian and thus their sister.
