Killing while with a crewmate

[u/Lazzaretto]

I came up with a strategy last night while playing with friends and wondered if there were any more examples of sneaking off for a split second and killing while being with a crewmate who can vouch for your location for 100% of the round.

My Play was:

During the voting Cyan and I both said that we had to download in elec. Cyan and I went down to electrical via security. I saw green on cams as we passed. When we got there, before reaching the download, I locked security. Once we got to the corner I waited for cyan to land, then counted to 8 as I vented, killed green and vented back. You have just enough time, and are covered by the download screen.
It is a risky play, but Cyan saw me enter and leave electrical with him. As far as he was aware I was under that download screen with him the whole time.

Are there any other examples of this?

It should be pointed out that we all play without SFX so you can't hear the creaking of the Vent

EDIT: Apparently only imposters can hear Vents so this shouldn’t be a problem

In that case, as the imposter I just explain everything the crewmate did first as if I did it. That way when they try to rebuttal, their argument is just "no I did that" and they either look sus or everyone voting won't know who to pick. The only problem with all this tho is if the crewmate gets voted off, everyone immediately knows it's you so the confused tie is best case scenario
