"Sometime after Young left again, the real Telford paid her a visit, but it is unknown what Telford's intentions were. (SGU
") A few months later, she asked for a divorce
from Colonel Everett Young
: "Trial and Error
"When Young came back for another visit, Emily was more sympathetic with his situation and even had sexual intercourse with him while he was in Col. Telford's body. It is strongly implied that she is having an affair with Telford - as himself, not containing her husband's consciousness - herself."
I thought it was pretty obvious.
Who are you quoting? It was a red herring. The cliffhanger of Earth
made it look that way, but we learn in Life
that he wasn't pretending to be Young at all, he was filling her head with crap about TJ and ruining their relationship as means of retribution under the guise of being a concerned friend involved in the whole Destiny mess. I suppose it's possible that she was lying, but Emily does state outright "...and I didn't sleep with him by the way, but thanks for not jumping to conclusions." when she was explaining to him what was actually happening.
This SGU discussion in an SG-1 thread reminds me what a comparative soap opera SGU was, not that that's a bad thing.
To be honest I'd say that says more about what passed for an adult relationship in SG-1 than anything.
