"Home" is a very important imagery in Gerard's lyric writing: "Can you take me home?"; "Never coming home."; "Nothing you can say can stop me going home."
He tends to attach great importance to it, especially in terms of the action of going home or taking/driving somebody home, as in Ambulance: "And if you save my life, I'll be the one who drives you home tonight."
Often, this word intentionally points towards Mikey. Brother and FLW need no further elaborations, and in the MV for The Ghost of You, he made the connection by referring to Mikey's "death." When he was thinking "I can never come home," he was talking about losing Mikey.
So in a pretty much cliche word, Mikey = home.
Mikey symbolises the most important thing in his life. He cannot leave Mikey; he needs to get back to Mikey over and over again, and he is afraid of being "left alone." As a matter of fact, I often think of Gerard as a kid who is very afraid of being "left alone". Still, he was never truly "alone" because he has always had Mikey." That's why the two times Mike left him, he was completely freaked out and mentally paralysed.
I often find this weirdly comforting and heartwarming.
Also, tell me Emily is not another song about Mikey.
