Haha I know! Junior would be such a good source of funny moments, it would make implementing humor easy and wouldn't take away from the story. Actually it'd be really cool if they end up stumbling onto him while on a mission in a old free lancer reaserch facility, or something like that. Junior could be like a teen living in the facility alone, and Tucker takes him under his wing and he becomes one of the reds and blues. He could be a similar character type to Lopez but without all the hatred towards his leaders haha. And Sister would be cool too if she just showed up every now and then. I'd love if at the resolution of the series, the reds and blues could return to blood gulch to create somewhat normal lives(or whatever there version of normal is), and they'd arrive to Sister and hundreds of other old Spartan IIs raving throughout the entire canyon haha, then cue some corny and nostalgic yet fitting scene between the remaining main characters and caboose -blam!-ing something up and then boom hit us with the original theme song and I'm satisfied.
