~12 min - pudge and sky are waiting in trees on the mid lane for some time while noone was even close
12 48 - pudge is standing right next to necrolyte but can't see him and hooks sniper instead (both die later because they didn't know necrolyte is there)
14 20 - pudge places observer on mid lane, sees sniper and hooks (thats when sniper accuses him of having maphack for the first time)
29 45 - sky wasn't "walking left and right", he went back a few steps to type a chat messenge right before you attacked him. Pudge passed right through you shortly before that going in the direction of rune and went back once you attacked sky.
33 - didn't see anything suspicious, he even let you teleport from the side shop, if he could see you he would have hooked you or blinked instead.
In general, pudge and sky were warding whole game and i didn't see a single suspicious action performed by them.
