i'll do some quick math to figure this out! joined in 2639, obviously jumped into the war in 2646, 2647 or 2648 ended up in the hands of the glf, and was 'released' in 2649 with the armistice back to adf where he likely remained for at most a year while he was checked out before hitting the civilian path on terminus in 2650 or 2651, so he'll have been there about 4-5 years as part of t-sec. they could've very well been military bros in some regard, though cael has got a few years seniority as far as enlistment dates go. i've yet to work on personality et al, but considering he's a sleeper, he's probably the same sort of guy as during the military (probably cocky, quick with a smile while charming, but might actually smack someone, all good living that military life) but with a few more war scars.
