Beta Hal time again !!!
Funniest course of action is Bro does not tell Dave about Hal’s existence prior to the body. Dave knows sometimes when he messages Bro it feels weird and different, but chalks it up to his fickle moods and maybe a Mind Game. And then one time when he’s 17 Bro starts holing up in his room WAY more than usual(already a Lot,) and then 1.5 yrs later there’s just a.
Fucking. Robot in his home who knows who he is. Surprise new older brother(??)
However. The likely course is that Hal has existed in text form long enough for Dave to get familiar and the body is instead a looming threat of having a second, even more annoying Bro in the house.
