Hell with protocols and propriety; there's no Command here.

It takes 2B a moment to respond, but when she does, she wraps her arms around 6O, relieved her operator is here. Emotions are prohibited, but it doesn't matter any more. She always wanted 6O to be happy.

Still, hugging isn't something that comes naturally to 2B, so she kind of awkwardly holds 6O while they both work through their emotions.
