From me.

"It looks like you need saving."

I can't say if I need saving, but you certainly do.

I need to save you- from myself.

I'm a time-bomb, and the clock's ticking. I need to get you as far as will be safe, from this explosive device.

I, on the other hand, cannot be saved. I'm a time-bomb after all, which has to but detonate. It's only fair.
