This is based on some RP madness on Formspring.
What happened was, Movie Megatron (having been resurrected by Armada Megatron) invited Armada Megs and TFP Starscream to come see the Hatchlings. He promptly set one on Screamer's shoulder (After Screamer had a 'sticky' encounter with Igor) and it immediately liked him.
The Hatchling likes Starscream, Starscream does not like the Hatchling. The Hatchling nuzzled his neck and purred.
Hope you don't mind the sketchiness
