Ethan Goodspeed, also known as Ethan Rom, is a fictional character portrayed by William Mapother on the ABC television show Lost. Introduced in the first season as the main antagonist, Ethan is the surgeon for the antagonistic and mysterious group known as the "Others".

What did Ethan do to Claire on Lost?

To distract his pursuers, Ethan hanged Charlie hanged from a tree ("All the Best Cowboys Have Daddy Issues"). Ethan then took Claire to the Staff and (presumably) drugged her repeatedly, giving her sour water and injecting her pregnant belly.

How did Ethan carry Claire and Charlie?

He had Tom with him when he came back for Claire and Charlie, which is how he incapacitated them so quickly, carried them both away, and was able to temporarily abandon them while he attacked Jack. Was sent by Ben to infiltrate the crash survivors because he had been in the outside world.
