Just need Garrett's dex checks then.  No one to aid you, I think?  I'm not exactly certain if we can each do aid another rolls, cause it makes sense to have an aid check, but to have someone being aided aid someone else?  That's a GM rulling.<br/><br/>And it looks like, your two misses are on different rounds than Sam's three.  So now we have to pray that Garrett makes all his, with your aid.
