Here is how Malfunction senses Flash Fire goes in Ryan F-Freeman's Adventures of Transformers: Prime.
[we see what's left of Code Red relaxing]
[we see Malfunction punching a punching bag, while memories of the past plague him]
Thomas: What's wrong?
Crash Bandicoot: What's the matter, M M?
Major Malfunction: I can't stop thinking about everything that went wrong with me. It's like-(suddenly, he senses something) I've just lost connection with Flash Fire
Crash Bandicoot: Come again?
Major Malfunction: I can't feel his presence anymore.
Thomas: That doesn't sound good.
Ryan F-Freeman: By jove. Maybe I can control I-Rex.
