Could Ethan Hunt bring down Jason Bourne?

Nope.

not alone, if he had his crew he would capture him. then he would realize that was what Bourne wanted and Bourne would escape.

Ethan Hunt couldn't capture a moment in a photograph, let alone Bourne.

After a long chase the MI team manage to corner Bourne in one of his supposed safe houses - and a massive fight ensues. Bloodied but unbowed 3 of the team sit on Bourne while Hunt
returns to their vehicle to grab some drugs that will knock Bourne out for 24 hours while they get him back to his own 'controllers'

Bourne starts to groan - his face is bloodied - it's then that Luther notices that part of his skin appears to be lose - he pulls it and to his horror the whole of Bourne's face comes off in his hands. Underneath is a battered Ethan.

The team then hear a car starting and pulling away at high speed. Bourne has escaped again.

Ethan then mumbles to his his team 'Well that's another fine mess you've got me into'
