T-Rex: If you live long enough, eventually you're older than most people. And on that day, you probably won't notice!

T-Rex: You'll just continue on as you always have, unaware that you're now mathematically An Old!

T-Rex: That's because you're likely to be surrounded by friends of a similar age, which hides the truth. But every day the faces you see on the street will be younger and younger than you. You can only hide it for so long.

Utahraptor: Until the day EVERYONE can tell you're older than average?
T-Rex: Exactly!

T-Rex: Eventually you become noticeable, first as "that old guy", then "that really old guy", then "that old guy, can he not die?", then "the immortal one who feasts", then simply as "Z'Xtolth the Inevitable".
T-Rex: And then you WIN.

Off panel: Yep! That's life for you!!
T-Rex: Can't wait!
