Then you can use the /scon or /scid command to cross the connection boundry.
/scid 1 msg hellofetish $nick said hello on $network
Also, keep in mind that $cid is a changeable value. If you open 3 connections, they will be numbered 1, 2 and 3, respectively. (And $scid(N) will match $scon(N).)
$scid(1) == $scon(1)
$scid(2) == $scon(2)
$scid(3) == $scon(3)
If you then close the first two connections and open two different server connections (with /server -m), now you have 3 connections open again, but the $cid's will be 3, 4 and 5, which does not match the $scon(N) anymore. $scon's follow the total number of connections you have open.
$scid(3) == $scon(1)
$scid(4) == $scon(2)
$scid(5) == $scon(3)
