Narrative:

Aircraft Y was given descent on initial contact and requested discretion, told to 'begin descent now and expect a restr.' aircraft X was climbing beneath another aircraft who reported ice and needed lower immediately. Radar associate trainee was very new, and him and trainer were not very helpful on pointing out emergency to approach. Meanwhile, I was spinning an arrival who also needed a pointout that had not been done. Aircraft Y was only descending at 500 FPM and was told to expedite turn. Aircraft X was told to expedite climb and turn. D-side cleared off a non radar departure and didn't advise me, automatic-acquired underneath another flight with the same altitude. Departure strip was not in the bay. My trainer said 'it's not working with aircraft's X and Y.' amended the altitudes, but they both had already gone through them. Supplemental information from acn 485600: training at cip sector ZOB (71) trainee fpl xferred from another facility with 4 out of 6 sectors already certified on, 10-15 hours experience at cip sector. Departures from pit inbound to pit which we were spinning one inbound for acceptance to pit. Departure off of dub airport within our sector that we work and up. Icing with another aircraft climbing in the departure flight path at pit, that needed a lower altitude. 16 data blocks on screen. Trainee was doing a good job until she forced the aircraft together. By the time she heard me say it wasn't going to work, stopping both aircraft, still it was too late.

ACFT X WAS CLBING BENEATH ANOTHER ACFT WHO RPTED ICE AND NEEDED LOWER IMMEDIATELY. RADAR ASSOCIATE TRAINEE WAS VERY NEW, AND HIM AND TRAINER WERE NOT VERY HELPFUL ON POINTING OUT EMER TO APCH. MEANWHILE, I WAS SPINNING AN ARR WHO ALSO NEEDED A POINTOUT THAT HAD NOT BEEN DONE. ACFT Y WAS ONLY DSNDING AT 500 FPM AND WAS TOLD TO EXPEDITE TURN. ACFT X WAS TOLD TO EXPEDITE CLB AND TURN. D-SIDE CLRED OFF A NON RADAR DEP AND DIDN'T ADVISE ME, AUTO-ACQUIRED UNDERNEATH ANOTHER FLT WITH THE SAME ALT. DEP STRIP WAS NOT IN THE BAY. MY TRAINER SAID 'IT'S NOT WORKING WITH ACFT'S X AND Y.'
