Kind of a weird two-part prompt, or I guess a different take on a prompt I've seen here once or twice. Desmond comes back as a computer program within the Temple. After the initial weirdness, he rejoins the team and everything seems like it's (mostly) normal again. But then something...happens. Maybe it's a power surge, maybe Juno catches up to him, maybe he tries to hack into Abstergo's computers and contracts a virus, whatever, but program!Desmond gets...glitchy.

He starts to skip when he talks, he goes through violent mood swings, bits of him start to break up into code, his Bleeding Effect (which would be gone after he comes back) returns and hits him hard, to the point where instead of making a hologram of his own body, he shows up looking like Altair or Ezio or Connor. The others naturally get freaked out and scramble to fix him before they lose him again.

(Bonus points if glitchy, Bleeding Desmond somehow manages to channel Clay.)
